Reference to a Movieclip inside another movieclip

Hello all!

I have afew movieclips on the main timeline, and now I need to make one movieclip from them all while being able to reference to them.

I got this code

function on_click(event:MouseEvent):void {
if (r && r.parent == this) {
removeChildĀ®;
bmp.stop();
}
if (scroll_mc && scroll_mc.parent == this) {
removeChild(scroll_mc);
}
}

How would I rewrite the code to make the script understand that I want to look inside the movicelip mc for the other ones?

Regards
