Uh, well. There's no "AJAX" going on in that demo -- it's just submitting
the values each time you change a SELECT's value. Use Firebug to
check the network traffic.

See #1  :-)

I'm not familiar with mootools -- is that a requirement for your project?
If so, I'm sure there's a library function to make AJAX requests easier
(and unobtrusive).

Also, the test page has an entire HTML document inside a table cell (!)
which probably isn't intentional -- e.g.

 <table class="contentpaneopen">
 <tr>
 <td valign="top">
 <!doctype html public "-//w3c//dtd html 3.2//en">
 <html>
 <head>
 <title>Demo of Three Multiple drop down list box from plus2net</title>

That won't be helping any JS-related development or troubleshooting!
