在主时间轴中的另一个内执行movieclip

I am trying to create a movieclip that will be used in other projects. It is actually the 15-puzzle game. I have every thing working except how to execute the movieclip when someone wins the game. Checking for win works so I know when I need to play the clip, I just don't know how. Every thing needs to stay under the Puzzle movieclip. I will attach the code. I am using the "false" win to test so I don't have to play the game everytime I want to test it. I am a 40 year vet of COBOL programming, but VERY new to Flash. What I need to know is: 1) Where to put the win_mc 2) How to call it from the mousedown handler where I test for a win 3) Comments on coding greatly appreciated. I want to learn Flash the right way.I am trying to create a movieclip that will be
