Tell targeting an mc on main timeline

hello people,
i have a problem with tell targeting. basically i have two mc on the main timeline and one(MC1) has a button burried in it. i want that button to tell the other mc (crystal) to play a label “editions” inside it.

my code is:

on (release) {
_root.crystal.gotoAndPlay(“editions”);
}

but it only works when the crystalMC is on the first frame of the root.

is there a way of telling the root to move to the position of the first mc and then play a label inside that mc?

any help greatly appreciated
