I looked around for a solution but could not find one. I am trying to find combinations of numbers that can add up to a total. The numbers available and the total are different each time.
For example, I have an array that contains the following numbers:
[16,12,8,6,4,2]
I want to find the combinations that add up to 140, like this:

how to add up a series of text boxes which contain numbers that a user will input and have the total of those text boxes show up in a quantity text box on the next page.
Not sure if i should use javascript or php, but i don't know how to do it either
Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.

I need to know how I would go about making it so that when people select an option like men it populates a different set of dropdown options in the second dropdown (and a different set of options if I select women, etc...), and then I can select an option like Hair Care Products and have it swap out the image in a div to show mens hair care products. I have code to do this for just one dropdown, but I don't know how to make it work with two dropdowns that populate different info based on the selection of the first dropdown.
<label>
<select name="menu" id="menu">
<option value="Men" selected="selected">Men</option>
<option value="Women">Women</option>
</select>
</label></td>

The code I will am including is far from finished, but some of what I do have works (the "submit" code does not work yet). I am able to prevent certain kinds of input including Shift-Ins pasting, but Ctrl-v pasting still works (and I do not want it to). Could you please tell/show me what code needs to be entered to my existing functions, or what new function I need to create (and call from my existing functions) to eliminate any kind of CtrlKey input?

I am trying to add up some fields, it works but to get the total you have to click on the total box. Is there any way of getting it to total automatically i.e. when the user enter a quanity it will show the total straight away without having to click the total box.

I used the sum of check boxes script, altered it for radio buttons and it works... except for one little nit-picking thing.If a user changes their mind and chooses the other radio button in the set, the total does not reflect the actual total unless they click again on an already set radio button on the side they are using.Here's the JS:
Code:
//Adds the sum of all radio buttons for the Home Team (Games Won)
function UpdateCost() {
var sum = 0;[code]......
How can I get this to reflect the actual games won if a user changes a radio button from home team to visiting team? I have a duplicate JS (UpdateCost2) and I have a matched pair of radio buttons for each game. Either you win (get 1) or lose (get 0).
When i comment off the document.autoSumForm.row7_col1.value = (row1_col1 * 1) + (row2_col1 * 1);
in cal() function it work the way i want it. I get the total in last column of each row. i am trying to get the last line ( Total ) of each column.
Here is my code.

I am having trouble writing this javascript for my work, normally I would do this in ASP or PHP, but the environment I am working with will only allow javascript for dynamic function.
The form has two different select boxes and based on your options selected for select box #1 and select box #2, the hidden input field "redirect" (which is currently empty) would then populate dynamically with the URL associated with that combination mentioned below. The hidden redirect input field (now containing dyanmically generated data) would then pass the new value via HTTP_POST to .net script that will handle the redirect processing step fed to it. code...
I have a page that lists a bunch of golf clubs. They are ordered by catagory (drivers, woods, etc) When you click on a check box the javascript puts the price in a sub-total box. I need it to also add up the total for the page.Here's a link to the page:
http:[url]....Here is the javascript at the top:
Code:
<script language=javascript>
var a=<?php echo $row_recDrivers['cPrice']; ?>; //set driver value.
var b=<?php echo $row_recWood['cPrice']; ?>; //set wood1 value.[code].....

I have a issue with a javascript code that I wrote. This script is a simply for calculating the summation of 2 text input boxes and printing it in another text input box within the form. The entire form is then sent using Form post.The total is written back to the form's total text input box using the code below:
document.getElementById ('total').value = total
This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.
1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.
My requirement is to develop a simple form with checkboxes which when selected calculate a price based on the value assigned to the checkbox. The form and calculations is working great but i need a few final touches which i can't work out.
1. I want the total to be in plain text and not in a text box maybe just drop the total value in a DIV.
2. I want the form to start with a default value for example 200, i have tried adding a hidden checkbox with a value of 200 and setting it to checked as default but it doesnt display 200 in the total when i first load the page it only calculates it when i select the first box and i need it to be displayed as the total even if no options are selected.

I need to modify the script showed at: [URL]
Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.
And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?
The code at the above URL is as follows:
<script type="text/javascript">
// initialise variable to save cc input string
var cc_number_saved = "";
</script>

Here is a sample form that I just made up. I would like a somekind of
script that when each button is checked or unchecked to dynamicly add or
subtract the total.

I am making what I call a PM (Preventive Maintenance) Kit list. My users will use this list to generate a printable sheet to tell me what they used out of there kit. The list includes pricing per part and I would like the list to calculate the costing as they enter each item. So a total per line and an overall total cost.
I have included a snap shot of the page and below is the code. I can do this sort of thing on a small scale with just adding two lines but I am not sure how to modify it to handle this scale. You can see the script towards the bottom of the page. That is my lame attempt to make the per line costing happen but NOTHING happens.

require "../config/bpts_config.php";

automatically calculate a total. The script pulls a price, which is given from a database to a hidden form field. Then once the quantity is changed the bottom form field automatically updates the price. Here's my script if someone could possibly point out why this might not be working (or is my logic flawed.)

How to subtract totalgift if my condition of donateamount is lesser than the totalgift trigger.
When the field is selected and the DonateAmount is trigger, I need to subtract the entered amount on the field selected to the TotalGift and put the field selected to zero "0" and TotalGift to original amount which is less than the amount entered on the field selected. I have some code that I created but it doesn't work. My initial javascript to calculate all the total is below assuming that DonateAmount is already selected = 25:
Below is what I am trying to do but it doesn't work. If the first input field is selected and user enter amount greater than the TotalGift, alert will pop-up then and the amount entered by the user automatically added to the TotalGift. So what I wanted to do is to subtract the amount entered to the TotalGift so it will go back to the original amount before the addition occurs. I know it is possible but I just can't get the right code.
My html code below which I have 18 input fields but all of them only optional wherever the user wants to input number. I will only include some here. Code below works, please ignore any missing code. I just need the calculation code to work.

I can get the number of contributers to add up but not the total amount of dollars they contributed. I am not sure if my function is wrong or if I am just confused with what variable to output for the dollar amount total.

I'm creating a web form that allows users to select from a list, choose a quantity and have the total for that quantity calculated, but when I run the html, I get Nan in the total price box. The problem starts with the calc price function. I've tried eval(), parseFloat to change the text to a number, but I think I'm putting the code in the wrong place.The first part is the javascript code (I have linked in a separate file) with the html below it.
window.onload = startForm;

I have a page that has a total field that will have a value when the page is loaded. I also have a few select options that modify the total via an onchange event. Problem is, when i change a select option twice, I cant work out how to get the correct total happening instead of just adding more to the total. I'll show you what I mean.. Code:
