You don't have anything telling it to load into container. Assuming this actionscript is associated with a button in a navigation or something like that, which then loads the content into a movie clip, this has worked for as long as I can remember.

on(release){
container.loadMovie("contact.swf");
}

I'm not using CS3 yet so I can't test this, it does work in Flash 8 (Published for Player 8, ActionScript 2).
