Movie clips on main timeline

HI! I’m using Flash MX and I’m not very good at it. So I would appreciate your help! Anyway, I’m making a movie w/ no interactivity and I want to put a series of movie clips on the main time line, each to play after the previous movie clip is done. The only way I can make it work is to put the movie clips in keyframes and then allow all all the frames for the movie to play. My movie is way too long and I know there has to be a better way! I’m trying to figure out the action to assign to the keyframe that will play the movie clip within that one frame and when it’s done, go on to the next movie clip. Is that possible?

Thanks to anyone who can help!
