Controlling SWFs

[oize]

Should be simple but...I can't figure this out!
I am attaching an external SWF to a movie clip instance with loadMovie but I can't control it. The SWF plays fine on its own so that's not the issue. It starts playing as soon as it is loaded. I am using myInstance.gotoAndStop() but it won't stop. Is there anway to control the SWF? I can manipulate the movie clip instance but it doesn't seem to affect the SWF.
Please help before I lose more hair.
Thanks.

You have to navigate through the amin movie too!
Like if you have the swf loaded into an mc:
_root.movie.mc [mc]
and in the loaded movie you would put it
_root.cumbaya.gotoAndStop(55);
then you'll just have to make it like this in the main movie:
_root.movie.mc.cumbaya.gotoAndStop(55);
That was just an example...
I hope you got it right :)

Thanks for the reply.
Sorry but I couldn't follow your examples.
Does the mc instance have to be as many frames in length as the SWF that is attached to it?
Can I not stop() the main timeline and just run the instance of the SWF?
