Buttons to MC's

I have 10 animated MC’s in my library. I would like the user to be able to select any of 10 corresponding buttons to play a movie of their choice, leaving the last frame of the movie up until the next button is selected. My buttons are on the stage, they have event-handlers and instance names attached. The MC’s are on the stage also with instance names attached. Unfortunately ALL of the movies clips are playing at the same time as soon as I test the swf. Obviously, I have skipped a very important elementary step. Can anyone help me or point me to a tutorial.

Thanks 8-]
