Nested buttons 2 levels deep not working from main time line

I was following the tutorial for the infinite menu http://www.kirupa.com/developer/mx/infinite.htm
it works beautifully except that the buttons don’t go any where!
and i couldn’t make them navigable with the little scripting that I do know.
any help would be appreciated

basically…
theres a button in an mc in an mc on the main time line and the button wont work. but if i put the button on the main time line it works so i know that its how I’m trying to call on it to goto the other scenes that is wrong.
