Can't make menu button call up mc and its frame (1)?

OK,
I have a main scene, then sitting in the root scene I have 2 movie clips.
1)centro
2)foto

In the first movie “centro” there is a menu btn
I want this menu btn to call up mclarge + its frame (1) thats housed 3 levels inside the foto mc in root.

Main scene - (1) centro (banner which houses menu btn)
(2) foto_mc

  • Main_boy_mc (<—works if menu btn houses in here)
  • mclarge

I WANT:

(1) centro menu btn to call up mclarge with specified framerate (1)

WHAT WORKS SO FAR:
When I have the menu btn from centro housed in Main_boy mc it works.
This is the current AS2 im using in this level-

on (release) {this._parent.mclarge.gotoAndStop(1);
}
on (release) {this._parent.mclarge_fade.gotoAndPlay(1);
}
on (rollOver) {mcthmbfade01.gotoAndPlay(16);
}
on (rollOut) {mcthmbfade01.gotoAndPlay(26);
}

Im sorry I know Im 5hi7 but im trying to learn…
