Showing What's on Stage Only

Hi,

When making a flash movie is there anyway to export the movie so it shows ONLY what was on the stage in the .fla, not everything in the movie, including everything outside the boundries of the stage.

I’m asking because I’m making a banner ad and when I load it into my main movie it’s showing stuff that was not on the stage in my banner ad .fla

Thanks for any help you can give me!
