What you need to do is this. Put your sound in its own movie. Then insert that movie into the MAIN MOVIE. Then make your button, and on the down state, insert an action, just so that it goes to a blank frame that has an instance of a button that looks exactly the same. But in that button have the down state go to the begining of the frame that the music starts on. If you just want the sound to restart, and not the movie, just put a stop action at the end of your movie, and then put another instance of the sound after the stop action, and just have the button reference that frame. This is the easiest way to do it without allot of scripting. Just out of curiosity did you send the pope an email? Have a great day, if you have anymore questions, just post it on the board.
