[thelist] flash code for buttons triggering simultaneous movie clips

[Rachel Starr]

I'm struggling with a flash question:
I need an open source ".fla" file that shows a series of buttons that
trigger an action.  This action will play the last 15 frames  of one movie
clip while simultaneously starting another movie clip.  The major issue is
that there will be 6 movie clips and each button needs to be able to tell
which movie is currently playing (so that the action will play the last 15
frames).

Any advice? Any code? Please help!
