Loading External SWFs

I’m doing the tutorial for “transitions between external SWFs”, but I’m having a problem because in the tutorial all of the buttons are on the main timeline, but in my site the buttons are on a different timeline. This is the actionscript that the tutorial tells me to use…

on (release) { if (_root.currMovie == undefined) { _root.currMovie = “work”; container.loadMovie(“work.swf”); } else if (_root.currMovie != “work”) { if (container._currentframe >= container.midframe) { _root.currMovie = “work”; container.play(); } } }
But that only works if your buttons are on the main timeline. How do I reference a different timeline? Any help would be greatly appreciated…Thanks!!!
