Looping Problem with External Files

Question

This is what I'm trying to build: A swf file (called main)
that loads 4 external swf files (called intro, one, two, and
three). At the start, main.swf loads the intro.swf, and it plays
once. When intro is done, main loads and plays one.swf. This will
loop until the user hits one of the buttons, and then two or three
starts playing.
What I have done already: Coded buttons. Code works.
What I am having a problem: I want intro.swf to play just
once, but it keeps looping. It's supposed to play once, and then
one.swf is supposed to start looping. Is there anyway to tell intro
to loop just once? (What I've tried already: a stop() function at
the end of intro.swf clip, publishing intro.swf with 'no loops'
setting.)
(Talk slowly; I have almost no idea how to code in
flash.)

Answer 1

Edit: Really? No problem? Weird.. I find that all of the
imported swf files loop infinitely, unless a stop() or
unloadmovie() function is called, but then I need another button.
Anyway, I found a workaround, that seems really obvious (in
hindsight): I just copied the Introduction file into a new scene in
the Main file. (Algorithm: Preloader, skip to Introduction scene,
skip back to main scene. External swf files load, depending on what
button the user clicks on.)
Even though it's sorted already, I'd still hear what code you
use. (It might be simplier than what I did.)
