Noob needing help to create simple presentation

Hey guys. I’m totally new to AS3 and would like a little bit of help doing a simple presentation. Basically, my FLASH movie is composed of 30 frames or so, each frame with it’s own JPG. On either side of the JPGs there are arrows to navigate back and forth in the presentation. It’s kind of like a power point presentation, but in flash. What I’d like to know is the proper actionscript to stop the movie from playing. I have the AS for my buttons.
i.e.


nextbutton.onRelease = function() {
nextFrame();
};

However, I can’t get my movie to just stop instead of playing every frame. Even if I were to write the AS stop(); function.
Any suggestions?
Thanks in Advance :afro:
