Slide and then play

Hello all-

I am at my wits end!:crazy:

I am trying to make a button which slides when pressed, and upon release will play the rest of the movie clip. Each time I have tried to do this, instead of just the slider sliding, everything in the frame slides also. It does, upon release, play the rest of the clip.

How can I get the rest of the elements in the frame to stay in place? (Does this make sense to anyone?)
