I'm not very good at explaining things, but I'll give it my best shot. If you still don't understand, I'll be more than happy to rephrase it for you. ; u;''

I have a layer on the file labeled "Stop Action." On each page frame, there's a keyframe on that layer with an action code on it. To do that, right click on the keyframe in the "Stop Action" layer, go to 'Actions,' and put this on the first line:

Stop();

Then, on a separate layer above the "Stop Action," I have one labeled "Buttons." While I have both buttons on the same layer, I have them split up into different keyframes across the comic. Each button uses the same code though, just a different frame number corresponding to the pages:

on (release) {
gotoAndPlay(FRAME_NUMBER);
}

Yes, there is a simpler code for this, but because I'm still a beginner in Flash, I use these codes. So far, they work just fine. Hope that helps!
