Code verification

Question

I am trying to get the playhead to move to a frame labeled
"features" when the cursor is held over a MC called features_mc.
The code below seems right but upon testing the movie I get an
error message that says "The class or interface 'MouseEvent' could
not be loaded." (it refeferences the function line). What am I
doing wrong?
Thanks,
Al
stop();
features_mc.addEventListener(MouseEvent.ROLL_OVER,
featuresText);
function featuresText(event:MouseEvent):void
gotoAndStop("features");
}

Answer 1

This would be the easiest way to do it:
features_mc.onRollOver =function(){
gotoAndStop("features");
