Targeting main stage for navigation 'scope'

Hi there,

I'm getting an error when it comes to using this.gotoAndPlay('end'). I have a label with 'end' so that I don't need to use frame numbers

Essentially, I have a few drag functions. The function 'finish();' fires at the 'mouseup' per drag (so right at the end).

Finish function looks like this:

function finish(){
     score++;
     console.log(score);

     if(score == 3){

          this.gotoAndPlay('end');

}
}

The score gets to 3 but then..

I'm getting an error on this.gotoAndPlay('end'). I assume it's because of the 'scope'..

Any help is greatly appreciated!
