Iframe SSI script II - Firefox Problem

[Mariam]

1) Script Title: Iframe SSI script II

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/iframessi2.htm

3) Describe problem:
I used Iframe SSI script II in http://www.it-innovations.ae/ . It's working totally fine with IE7 while the scrollbar is appearing in Firefox! How can I fix this issue?

P.S: I used the same script in another website and I didn't face such problem!

Thanks in advance.

I solved the problem! :)
I changed IFrame overflow style from visible to hidden:

style= "overflow:hidden; width:100%; display:none;"
