button targeting seems so obvious, but not working

[SwirlyKing]

I'm thinking this should be so simple, but I can't get the scaleX to work.

fishName.infoBtn.addEventListener(MouseEvent.CLICK, fishClick);
function fishClick(e:MouseEvent):void{
    btnClick = btnClickSound.play();
    fishName.infoBtn.scaleX = .1;
} 

[fx.barrett]

// disable the children of "infoBtn" so they won't react to the click event
fishName.infoBtn.mouseChildren = false;
fishName.infoBtn.addEventListener(MouseEvent.CLICK, fishClick);

function fishClick(e:MouseEvent):void
{
    btnClick = btnClickSound.play();
    e.target.scaleX = .1;
}
