Control a MC position based on mouse point

Hello again,

I am trying to make an animation where the user can mouse over a small MC at the top of the stage, which controls the movement of another larger MC at the bottom of the stage.

I am thinking that ‘points’ (which I know nothing about) might be the way to go. The other thing is that it needs to be fluid motion. Am I at least on the right track with points and mouse_move or is there a better approach for this?

Thanks for the help.
