I've got an error in my code and I don't understand code help?

​ADOBE ANIMATE​

I'm new to coding and I don't understand it. I'm using AS3 and i'm trying to make a pause and play button in my game so I typed in this code:

yourButton.addEventListener(MouseEvent.CLICK, pauseGame);

function pauseGame(e:MouseEvent):void{

     stage.frameRate = 0;

}

yourOtherButton.addEventListener(MouseEvent.CLICK, resumeGame);

function resumeGame(e:MouseEvent):void{

     stage.frameRate = 15;

}

and it's giving me errors:

I don't know what this means...

(the part that is in Bold is the code it has a problem with) The full code is:
