Help... please.

Hello, here is my problem I have a movie clip which contains a button. This button needs to either play back the last 6 frames in reverse and stop, or play the next 6 frames then jump back 12 frames and continue playing. I would be very great full for any help. (I'm very poor at actionscript so dumb it down for me)
Thanks for any help.

For the backwards bit, add this to the button actions:

on(press){
	_root.GOBACK(this);
}

on the main timeline, add this function:

function GOBACK(mc){
	mc.cnt=0;
	mc.onEnterFrame=function(){
		if(this.cnt<7){this.prevFrame();}
		this.cnt++;
	}
}

For the going forwards bit, add this to the button actions:

on(press){
	play();
}

Then add this to a frame in the MC, 6 frames on from where the button is:

gotoAndPlay(_currentframe-12);
