Using Flash buttons to navigate HTML frames

Hi,
I find this site very useful and instructive. It truely is a great piece of work.
Anyway, I have a problem involving flash menu buttons in a frameset. I have consulted the protocol from kirupa, and the site works great when its on my desktop, however, after having uploaded it to my webspace, the site does not function. Now, it could be a problem with my hosting, but I have a feeling the actionscript is not sound.

If you would like to see how far I have gotten, visit: http://www.uweb.ucsb.edu/~awebster

thank you all! you guys are great.
-Alexandre.
