Changing Scenes

The animation starts playing automatically (scene 1, frame 1) and then I have it stop on frame 35 (using the stop () ). At that point the viewer is supposed to navigate and click on one of the three buttons. Once that happens I would like for the rest of scene 1 to play out (all the way to frame 75) and then depending on what button was pressed skip to SCENE 2 (button 1), SCENE 3 (button 2) or SCENE 4 (button 3). So in essence what I need is an action script for each button that would have the following logic:

BUTTON 1: if this one is pressed play the rest of SCENE 1 and once you reach the end go to SCENE 2
BUTTON 2: if this one is pressed play the rest of SCENE 1 and once you reach the end go to SCENE 3
BUTTON 3: if this one is pressed play the rest of SCENE 1 and once you reach the end go to SCENE 4
