How to make it play Somthing outside of the mc

I have a MC and it has a button inside, and I need it to play somthing on the main stage. I think the code is somthing like this but im not sure

on (release) {
 _root.gotoandplay("more");
}

And more is a frame label on the main stage, and the thing that is getting pressed is inside a movie clip.
Thanks,
