AS3 Play contents of a symbol

I've grouped a multiple layer 1 frame actionscript driven animation into a symbol. (simply put, imagine a 1 frame image being tweened by code over a few sec, in this symbol)

Now I'd like to play the contents of this symbol using an event listener.

But

stuff_mc.gotoAndPlay(1); and Test Movie doesn't play a thing (doesn't even show the contents of the symbol (the picture) which can actually be seen开发者_C百科 on stage).

If I go inside the stuff_mc and Test Scene, it works perfectly..

So how do I play stuff_mc from the stage?

Thanks in advance

It sounds to me like you are using multiple scenes. If that's the case then this is most likely where your problem is. Scenes are generally a bad idea in Flash – Adobe itself admits this.
