Controlling sound confusion

This is what i have, a music.swf file that contains the music controls and mp3 that function perfectly fine when tested by itself. I then have an index.swf that loads this music.swf into a blank movieclip on the mainstage of the index.swf However, when i go to play the mp3 (contained in the music.swf that is now loaded onto the index.swf) there is no sound whatsoever. I followed Kenny Bellows tutorial

yet, it still doesn’t function. I’m thinking i need to load the mp3 on the index.swf also, but i’m not sure. I hope i explained myself somewhat clearly. Any help at all would be much appreciated.

Take care.
