which doc type?

[TinyScript]

I don't know what the problem is. It validates, but won't work. the same script on another site works fine. How do I know what the server is using or which doc type to use when it validates?
here's the bad site
http://stirfrydesign.110mb.com/index.htm
and the working site
http://h1.ripway.com/stirfry/index.html

No errors. ....Side question, how do I know what firebug version to get...new thread

Your XHTML doesn’t validate.
Look at the JS/CSS error console (e. g. the one built in in Firefox), it shows some errors.
Also why are you using CDATA comments for the CSS? This ain’t necessary.

As to Firebug: What kind of question ist that? You’ve gotta get the latest version, of course (usually that’s the one directly linked to).
