Intermediate Actionscript Help needed

Hi, I am in need of some actionscript help. I’ve bee hacking away at Kirupa’s tutorial on dynamic thumbnails (http://www.kirupa.com/developer/mx2004/thumbnails.htm) trying to get them to seamlessly loop but I am a beginner at this. What I am trying to make is a scrolling thumbnail menu that is xml driven for unlimited thumbnails. I want it to behave like the one on http://www.karmaloop.com
