New to AJAX, trying to get simple form to work

[Naez]

I'm working on an RMA form for somebody.

 

Basically, you can see it  at http://naez.myftp.org/rmaform.php

 

Now what I want it to do, is when Ebay is selected, the Ebay item number will show up and the paypal will show up.  As you can see it kind of does that already.  Problem is when form is submitted with ebay selected, and there's errors so it doesn't go through, the div's hide again.  Also, in firefox if you click on the ebay radio button a bunch of times the layout gets messed up.  In IE it just says "Error on page" in the status bar but doesn't ruin the layout.

 

The framework I am using is http://naez.myftp.org/form.js .

 

Can anyone help point me in the right direction of doing this?

I got it working from this tutorial

Also I guess it was just js not ajax.

 

 

But now it is only displaying the first set of textboxes.  I need it to show 2 textboxes for every item #
