After one MC plays, the next plays

so i have 2 movie clips, and i want one to be in frame 1 of the main timeline, and the other mc in frame 2. i want the 2nd MC to play when the first MC is finished playing. i tried putting a stop in frame 1 of the main timeline and a level0.gotoAndPlay(2); at the end of the first MC so it would go to frame 2 of the main timeline after it was done playing. It is not working for me, maybe im doing something wrong, any ideas?
