I have createed a movie, which can be viewed here http://sk8photos.com, I
would like to add buttons that will let the user go to a prev frame or a next
frame. can any one direct me on how this can be done.

prevBtn.onPress=function(){
prevFrame();
}
nextBtn.onPress=function(){
nextFrame();

For basic Flash and Actionscript questions, I recommend the big yellow and
black Flash Bible. I'm pretty sure you can pick it up at Borders or Barnes &
Noble, and it's answered about 95% of my Flash questions since I started using
the program several years back.
