Stuck on movie clip "goto"s!

1

Okay, My movie is a little needlessly complex. I have my main movie, which has stop(); on frame 60, and there is a movie clip instance that starts on 58 (constant_mc, instance name: c1) and continues to play. I then have a movie clip INSIDE constant_mc called run_mc, which starts on frame 80 (of constant_mc). constant_mc has a stop(); command on frame 81. Is there any way I can get constant_mc to loop back to frame 3 when run_mc is done playing? I have a c1.gotoAndPlay(3); at the end of run_mc, but I don’t think its picking up the main timeline’s instance name. Sorry if that is confusing, but I’m sorta new to Flash and trying to pick things up.
