Controlling a Movieclip within a Movieclip

1

Hello

I am sure this is easier than I think, but I am having problems nonetheless.

I have a single button that I would like to control a movieclip (MC1) and the another movieclip (MC2) within it.

MC1 and MC2 are the movieclip instance names.

MC1 and the button are on the main timeline.

I am able to stop MC1 but not MC2

Here is the code on the button:
on(release){
stop();
MC1.MC2.stop();
}

Here is a simplified example illustrating my problem:

Any help would be appreciated
