on(release) {
score = score+1;
gotoAndPlay(3) ;
For the incorrect answer, you would just click to advance to the next frame without adding to the value of score:
on(release) {
gotoAndPlay(3) ;
Repeat this on every frame where you have a question save for the last, simply raising the frame number in the gotoAndPlay command by one so that it advances one frame/one question at a time. Leave the last question, as were going to do something different with that.
