why don't you stick your whole page up here - in an attachment if its very big. this problem is getting quite frustrating for me cos whenever i test anything - it works!
it must be the way you're integrating the scripts we're suggesting into your page, cos on their own they usually work fine.
post your html page (or email it me email@example.com
if you don't want it open on this forum), then i (and others) can try and find out what the problem really is.
