Alternative to attachMovie?

Is there an alternative to attachMovie that I can use to put my movieclips on to the stage. Here is my problem, I have 2 frames total in my fla file, and in each frame I have buttons that when you click on them it attaches the corresponding image from the library. Problem is when you click to go to the next frame, the attached image stays.

I basically want it to stay attached only until you hit the next frame.

thanks for all your help!
