Moving movie clips to different sections

In my current flash movie, I have 5 horizontal buttons, and when I click 1 of them, I would like for a movie cliip to move horizontally to that button. So pretty much I need help figure out how to movie that movie clip to the different buttons when they are pressed. But only horizontally. And it’d be nice if there was some easing invovled. Does anyone know of a tutorial that would help me? Thank You
