same jquery code works on one domain but not another

same jquery code works on one domain but not another

Hi -- I can't figure this out for the life of me. Trying to implement someone's simple drop-down menu code. I can't get it to work on the site I'm working on:


But the code works fine here: http://cheshiredave.com/ddtest1.php

The code is exactly the same. I've tried several different approaches to noConflict, and that doesn't appear to be the issue. This has plagued me for many hours today. Any ideas?

PS: I'm really sorry the source code on the broken site has no formatting. That's a separate thing that's plaguing me, why source on one server retains its formatting fine, and on the other server loses all line breaks. The only variable I can think of is the two sites are on different hosts, though the host of the problematic site (InMotion) says it's not their issue.
