JQuery :: $.load On Form Pages - Can't Get Query Data In Processing Script

I have a database site I am currently designing, and would like to use a single page with forms in external html documents to undertake admin tasks (eg. add/remove records etc.)

I have managed to successfully load the form html into the necessary div using the $.load function, however, when I try to process the form, with this code:

$("#add_form").validate({
debug: false,
rules: {
maker: "required",

[Code]....

which asks 'process_form.php' to process the data, it doesn't seem to send the data in the form to the page. to confirm this, and whilst trying to get the system to work, the 'process_form.php' consists of 2 lines,:

echo $_GET['maker'];
echo '123456';

(ie. one line to return a string literal, and one line to return one of the variables which SHOULD be passed by the form)

This results in just the 123456 string being returned.

I have tried several things: loading the script above in the head of the 'parent' html page (ie. which the form is loaded into); - does not properly fire at all;

loading the script 'in-line' in the imported html - this leads to the result given above; running the script in an external script.js file through an onsubmit directive on the form...does not appear to properly fire the script.
