Button inside movieclip not working properly

Hi -

Goal: I’m trying to create a menu bar that will let me view movie clips depending on which button I select.

Problem: At the start of the main timeline when the menu bar appears, I clicked on one of the button on the menu bar, and it takes me directly to a movie clip associated with it. While in the middle of that movie clip, I want to click on the same button (on the menu bar) again to take me to the beginning of that movie clip. However, when I did it the second time around, nothing happens.

On that button, the action is:

on(release) {
_root.gotoAndStop(2);
}

On the movie clip timeline, play(); is in the action layer on frame 1.

If I’m in the middle of the movieclip (that is in frame 2 of the main timeline), how come when I click on the button, it does not go to _root --> frame 2 --> play movie clip --> start at the beginning???

Any help is appreciated.

Thanks.
