flash actionscript: Can someone tell me how to synchronize two instances of the same movie clip?
More specifically, I have two instances of MC1. The first instance is running
in MC2, the second is running in MC3. Both MC2 and MC3 are embedded in the
main stage. Is there a way to keep the two instances of MC1 in synch, so that
the same button click will move both instances to the same frame?

Thanks for any help.

just apply code to whatever buttons you want to control those movieclips. for example:

on(press){
mc2.mc1.gotoAndPlay("whatever");
mc3.mc1.gotoAndPlay("whatever");
