Loop action

HI !

I’m creating an animation but I’m having problems with a loop.

What I want is to create a button (or movieClip?), that will make move Down another movieClip continuously, until the mouse stops pressing the button (or movieClip?).

Basicly I want to create some kind of loop that will be started wen I press a button, and stops wen I release the button.

The code I want in the loop is:
pagina._y += 10;

I’m using Flash MX Professional 2004, ActionScript 2.

Can someone help me?

Thanks.
