Javascript Script Help - IE Bug fixes needed

I need someone to fix a script on a webpage to make it work on IE5 and IE6. It currently works flawlessly in Firefox, Safari, and Chrome, but has a few bugs in IE5 and IE6. Please see attached documents for further details of what I need fixed. The script was written by me in javascript/ajax. You are responsible of copying the script on the site to your own development area. When you are done, please tell me what changes I need to do to my javascript, html, or css. Please let me how fast you can get this done.
