SwapDepths and LoadMovie

I have a main movie with 5 buttons that launch seperate .swf’s (loadMovie).

They are draggable, but I can’t get the swapdepths to work.

Main movie button 1:

on(release){
	loadMovie("pop1.swf", 40)
}

Main movie button 2:

on(release){
	loadMovie("pop2.swf", 41)
}

popup 1:

on (press) {
	_root.pop1.startDrag();
	_level0.mydepth += 20;
	_root.pop1.swapDepths(_level0.mydepth);
}
on (release) {
	_root.pop1.stopDrag();
}

popup2:

on (press) {
	_root.pop1.startDrag();
	_level0.mydepth += 20;
	_root.pop2.swapDepths(_level0.mydepth);
}
on (release) {
	_root.pop2.stopDrag();
}

I attached my .fla’s
