Flsah player6 as1 VS player 7 as2

smash

ok, here's the code. It works in player 6 as1 or even player 6 as2 but not player 7 as1 or 7 as2 which is what I want. I've got it to work before and I know it was something simple but you know yourself! I've been looking for ages and I know it's staring at me but I'm numb to it at this stage....

It's an andy foulds playbackwards script!

here's the script for the first frame:

movieclip.prototype.back = function() {
this.onEnterFrame = function() {
this.prevFrame();
if (this._currentframe == 1) {
delete this.onEnterFrame;
}
};
};
movieclip.prototype.forward = function() {
this.onEnterFrame = function() {
delete this.onEnterFrame;
this.play();
};
};

then you put this on a button

on(rollOver){
mc.forward();

}
on(rollOut){
mc.back();
}

and just have any mc on stage with the instance "mc" and place an animation inside it with a stop(); on first and last frame!

any ideas?
