Loaded swf help!

Hello could someone please help.

I have done the kirupa tutorial on transitions

All works fine untill I do something to the loaded swf.

For example if I click a button on the loaded swf the button works but then when I click the button on the main movie to load the next and play the transition the transistion doesnt work.

If I dont do anything to the loaded swf the transitions work!
Strange!!!

Is it something to do with the paths being changed when the loaded swf is acivated?

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

Then the code at the end of my swf to load the new one is

_root.container.loadMovie(_root.currMovie+".swf");

As i said all works fine untill I do something to the loaded swf. The new swf loads fine its just the outro doesnt play.
