Zooming in and out

Hello everyone!

I need some help with creating two buttons that zoom in and out of a movieclip.

I have seen some tutorials and tried them, but got really confused.

My problem is that the movieclip i want zoomed (in & out) is embedded inside another movieclip, so don’t know how to refer to it.

also where should i declare the zoom function?? on the movieclip or on the main timeline?? the buttons that control the zoom in and zoom out are on the main timeline.

I would be very thankful to u guys, if you could tell me the easiest way of zooming.

many thanks

E
