Button to advance

[unseth]

I have a flash file that is basically a slide show that continues to go through the pages. I would like to have four buttons on the bottom of the page:
Rewind - 48 frames
Pause - I have this working
Play I have this working
Fast Forward - 48 frames
What is the action script to advance or decrease the frames? I have tried gotoandplay (++48); but get an error and (+48) takes me to the 48th frame.

Thanks

Fixed with:
setting the Rewind button to:


on (release) {
gotoAndPlay(_currentFrame - 48);
}and setting the FF to:

on (release) {
gotoAndPlay(_currentFrame + 48);
}
