GoToAndPlay in clip

I’m new with flash and i have a little problem.

First, I have an Intro with 3 buttons when the intro finished. I put my intro in a CLIP and I dragged the clip from my libriary to my scene1. After this, I was unable to click on my buttons to go on my other scenes (scene2, scene3, scene4). I tried _root.GotoAndPlay(“Scene2”,1) put it’s seems I can’t gain access to my other scenes since I trun my intro in CLIP. Can anyone know how do it?

thank you
