Btn inside mc to trigger second mc without

I need several buttons to be within the one mc, having an action (zoom + scale) apply to all of them together. But each button should trigger a second mc that is not within the first mc. (because the second mc should be scaled and zoomed along with the first mc.)

So: button placed within mc. What action script to assign to the button to trigger an event not within the mc. ??!!

Does that make sense?

thanks. thanks. thanks.
