Playing MovieClips One by One

Hello,

I am trying to play a couple of movie clips one after the other one. In other words, I would like movie clip A to run and execute the AS attached, then I would like movie clip B to run and execute the AS attached to it.

Can anyone help me with how to get a movie to play and execute AS on one movie, then the next, then the next?

Thanks,
