Complex Button tutorial doesn't work...?

I went over the complex button tutorial and even downloaded the FLA at the bottom and copied the action script for the movie…and the button still didn’t work.

When I hit ctrl-ent to test the movie the image just sits there and does nothing as if I just put the symbol on the page and not the movie. Needless to say, I’m frustrated…but hopefully someone can shed some light on the subject.

Thanks!
