Movieclips to the highest level?

Hi,

I have 3 different movieclips loaded to the stage. Placed on different layers when I press the button which is associated with the right movieclip I get working only the one that sits above all. The rest is being played in the back of this movieclip.

I have 2 solutions in mind, I hope you guys could help me at leas with one of them.

-I have prepared a fade out inside each movieclip but why I am new to AS3 (I used AS2 before) I can’t figure out how to trigger this when another movieclip started to play.

or

-To get the actual movieclip placed on the highest level when a button is pressed.

Thanks!!!
