I am trying to create a monthly mortgage calculator, I have been able to make it show prompts for Amount of loan; Interest rate; and Term of loan (in months), but it will not display the results. Below is the code I have utilized to get this far.

Where could I find a mortgage calculator script I could place on my website? I found a really cool one at www.dave.imarc.net/php free to use but I have a hard time understanding how to install it. I really don't even know what php is.
Could someone maybe guide me out of this programming lingo darkness?
I've been trying to write a Javascript Mortgage Calculator for the past day and I believe I've got the structure right, although for some reason my functions must not be operating correctly or are not being called correctly. I'm almost afraid to say that it could be an error in the functions usage within the while loop. This Mortgage Calculator uses the principle of "bisection" to guess at the monthly payment necessary to fulfill the standards of the mortgage in question. This means that the loop is used to consistently halve the value of a guess until the correct monthly payment is guessed. Here is the code:
<script type=text/javascript>
function calcMortgage (amountText, yearsText, interestText) {
// constant definitions
// variable declaration
var amount = Number(amountText);
var years = Number(yearsText);

I am trying to place a Body Mass Index Calculator on a web page. I need a prompt box that asks the user to enter their weight and height (in pounds and inches, respectively). The box should calculate BMI as follows:BMI = (Weight / (Height * Height) ) * 703;After the BMI is calculated, I would like the box to display the user's status (obese, overweight, normal, underweight). After the user has entered all information, use the document.write function to display the following, with the customized information:
Height
Weight
BMI

I am using frames - yes frames - I do not know how to do anything but and I
know that there is better out there......but........
I am trying to set a frame so that it automatically puts a page
corresponding to the month in that frame (a calendar) Code:
i want the code below to display the total loan repayment amount instead of the monthly payment payment = principle * monthly interest/(1 - (1/(1+MonthlyInterest)*Months)) , eg if if l0an is 20$ payment is in 4 months, intrest rate is 15% display = amount to be repaid.

I'm trying to create a mortgage payment calculator in Javascript and am having problems. My algorithm seems correct but it's not giving the right results. Im using this code:
function do_calc_payment(){var term = document.calc_payment.term.value;var rate = document.calc_payment.rate.value;var amount = document.calc_payment.amount.value;var j = rate / (12*100);var m = term * 12;var payment = amount * ( j / (1 - (1 + j) ^ -m))var result = "$"+Math.round((payment)*1000)/1000;if(isNaN(payment)){document.calc_payment.rate.value="";document.calc_payment.amount.value="";result="Not a Number";}if(payment.length>=15){result="Max Characters";}document.getElementById('new_payment').innerHTML = result;}
Does anybody know of an algorithm to calculate mortgage payments? e.g.
Amount: 100,000
Interest Rate: 4.5%
Term: 25 Years
Monthly Payments: x
I've looked at other js scripts to do this but it seems alot more involved then I thought, and because they use non descriptive variable names I can't work any of them out..
I have a mortgage calc that is adding an extra decimal place to my interest rate. To see this in action go to: [URL]
Change the interest rate to 7.5
Click Calculate Payment
Click Create Amortization Chart
On the following screen you'll see a recap of your data and the interest rate will now say 7.55. Same thing happens if you enter 6.2. Next screen shows 6.22/. I've attached the html and js files in a zip.

I'm trying to make a calculator app; with a few differences. I have a text field with a numberpad below it, I got the numbers to show up in the text field, but am unsure as to how when I hit the enter button - it would store them in a variable?...I am also wondering as to how it would store current value and then allow me to input another value(maybe on the next page) and either subtract or add to it(the first value that is stored).I am also wondering how to get a decimal point in place(need it for currency).

I am trying to create a price calculator that automatically calculates the price of custom made picture frame. I got an equation that finds the square area of the frame by multiplying the perimeter (2*length*width) by the thickness (which the user can choose from 1.5", 2" or 3"). Then it multiplies it by a decimal number (0.27 if the frame is 1.5" thick, 0.23 if its 2" thick, and 0.18 if its 3" thick). Then it adds a $5 custom made fee to the final answer. But when I save it to an html file and load it in Internet Explorer, it doesn't calculate. Code:

I'm attempting to create a shopping cart shipping calculator using the total $ provided by the cart itself (%total%). Basically the script needs to take the %total%, compare it to a bunch of arrays in the javascript, and provide the shipping charge as a percentage of the total. For example:
The cart total ends up being $15 (or %total%).
The set rates for shipping are:
Standard Shipping
$1 - $4.99 : 7.95% (of total)
$5 - $9.99 : 9.95%
$10 - $19.99 : 11.95%
Overnight Shipping
$1 - $4.99 : 9.95% (of total)
$5 - $9.99 : 11.95%
$10 - $19.99 : 19.95%
Two radio buttons would show the 2 shipping options and the shipping charges like this:
O Standard: $1.79
O Overnight: $2.99

I am trying to implement a time calculator onto my website with preset times to tell how long it would take to make troops. Say you want to make 100 Catapults and each Catapult takes one minute and ten seconds to make, I would like to be able to show the time in days /hours / minutes preferably in the format of 0:00:00. I would like it so someone can type in the amount of troops they want. There are Infantry that take 0:00:22, Cavalry that take 0:00:52, Archers that take 0:00:35 and Catapults that take 0:01:10.
