Won't read variable

1

I have a MC on my stage. It has let’s say a motion tween that covers the stage when you click on a button. At the end of this motion tween we have a loadMovie (it loads a external swf). Then after that we have another motion tween that reveals the stage this time (showing the new swf)

My problem is that I don’t want the animation in the swf to start until the motion tween that reveals the stage is complete.

so what i did was at the end of the motion tween that reveals the stage i put


_global.myFlag=3;

then in the first frame the of movie being loaded i put


stop();
if (myFlag==3) {
    blah blah ...
}

this does not work … anyone know of a different way or why this is not working?

Cheers
