Running Multiple Javascripts

I’m creating my portfolio website and currently have it set up in a div that slides with javascript code. That works fine. However, to display my photos, I decided I wanted to set it up in this very nice viewer,
http://yoxigen.com/yoxview/usage.aspx
It works perfectly when I have just my test page and when it is in the folder you download from the above site. When I try to add it to my sliding divs, it no longer works. I’ve copied all files from the yoxviewer’s folder to my root folder. No luck. I’ve relinked all javascripts and css files. no luck. I thought it could be a javascript conflict. I’ve looked but don’t see onPageLoad or the usual suspects.
Any suggestions?
