alright I am desperate for help!!
for all of you who have some actionscript knowledge in Flash...

I'm designing a slideshow for my artwork. I used the tutorial here

Now I followed all the directions and the forward button works perfectly. Below is the script I used:
on (release) {
currentSlide = currentSlide + 1;
play ();
}

The previous button, however, doesn't work at all. Below is the script I used:
on (release) {
currentSlide = currentSlide - 1;
gotoAndStop ("slide"+currentSlide);
}

Does anyone have any idea what I'm doing wrong?
PLEASE HELP!!!!
thank you so much!
