Exponential Class error

I'm trying to use this function:



function scaleUp(event:MouseEvent):void {

TweenLite.to(event.target, 1, {scaleX:1.5, scaleY:1.5,
ease:Exponential.easeOut});

}

function scaleDown(event:MouseEvent):void {

TweenLite.to(event.target, 1, {scaleX:1, scaleY:1,
ease:Exponential.easeOut});

}



And am getting an error on the output:



1120: Access of undefined property Exponential.Exponential Class error
does the tweenlite class have exponential easing?Exponential Class error
I figured it out.



I had to add:



import fl.motion.easing.Exponential;
