Fist (in FireFox) press CTRL + SHIFT + J and load the Error console. Clear the contents before you reload the page. When you reload the page, if errors appear, fix them.

Is the call jquery ajax call being made? If you're using firefox, install the firebug extension. This extension will allow you to look at the ajax calls that are being made. It will make it easier for you to debug.

Also, jQuery offers a much simpler construct for ajax.
