Kirupa transitions tutorial question

http://www.kirupa.com/developer/mx2004/transitions2.htm

I really want to use this but unfortionatly my navigation has buttons in aother MC. Anyone know how I can still use this and not have all my buttons on the same level.

Here is the action script from the button:

on (release) {
if (_root.currMovie == undefined) {
_root.currMovie = “section2”;
container.loadMovie(“section2.swf”);
} else if (_root.currMovie != “section2”) {
if (container._currentframe >= container.midframe) {
_root.currMovie = “section2”;
container.play();
}
}
}

Cheers
