aaaaaaaaaand i fixed my own mistake again, lol. if you’re interested, it was this:
workStart.onRelease = function() {
this.play();
_root.index.onEnterFrame = function() {
if (this._currentframe == 15) {
delete this.onEnterFrame;
} else {
this.prevFrame();
}
};
};
again, thanks so much for your help.
