Answer 1

You seem to be trying to mix PHP and JavaScript syntax in your AJAX request URL.

If you're trying to send val as a GET parameter to a PHP script, you're going to have to do something like this:

new Ajax.Request('Website.php?cat=' + escape(val), 
  ....

and so on. Then, on the server side, you'll need to look for

$_GET['cat'] 

to get that value back.
