Could someone please help me?

When I export my movie for Quicktime (.mov), the mp3 I have in it disappears
and there is no sound! I am using Flash 8 Professional. I have a Quicktime
movie imported into my movie, so I'm pretty sure that I have to export it using
Flash 5 as a Quicktime movie in order to view the Quicktime movie that exists
in my movie (in imported moive doesnt show up when I export the whole thing as
html or swf). The movie itself works when I export at .mov, there is just no
sound at all. I have an important audio track that is basically the point of
the movie.

Any help would be really really appreciated. Thank you!

I realized I posted this in the wrong forum. BUT, you all are so smart and advanced in Flash, maybe someone could still help me?
