Movie clip + button = problem - why?

3 Scenes are going in following order - Scene1, Scene2, Scene3.
In Scene 3 there is a Movieclip (MC) which contains a button. I need to assign a code to that button in order that it takes me to the frame1 in the Scene2.
Problem: if I use

on (release) {
_parent.gotoAndStop(1);
}

or

on (release) {
_root.gotoAndStop(1);
}

it takes me to the Scene 1, but I need to get to the Scene 2. Please help.
