I'm fooling around with the dhtml script from http://www.dynamicdrive.com/dynamicindex1/topmen3/index.htm

And it looks good when i preview it on a webpage from my harddrive, but when i upload everything to my website(all in one folder, mind you) it doesn't show it and gives the error that 'exclude' is undefined.

What's wrong? I checked my mime types and js was listed. So i don't get it. I even chmoded all files 777 to make sure.
