Animated Collapsible DIV v2.4 is not working IE browser

1) Script Title: Animated Collapsible DIV v2.4 is not working IE browser

2) Describe problem:
I am using same script (Animated Collapsible DIV v2.4) in my application, it is working correctly in FF but not IE. I mean animation is working in FF not in IE.
I am using same script provided in below URL:
http://www.dynamicdrive.com/dynamici...edcollapse.htm

When I use this script in static HTML it is working correctly but if I use the same in Java application it is not working. Basically I need to show/hide a div using some fade effect (animation). For this I am using some separate JS file where I have loads of conditions defined to show the DIV. In same JS file I am invoking v2.4 script, all functionality is working correctly but animation/effect not able to see in IE.

Can anyone help me on this issue.

Thanks

Is this a bug report? Does this problem occur on the dynamic drive demo page?
If not, you should post this in the "Dynamic Drive Scripts Help" area, NOT bug reports.

It sounds like you are having trouble creating your own version, so you should post this there.

Also, if you want help (and it is NOT a problem with the original script):

Please post a link to the page on your site that contains the problematic script so we can check it out.
