ActionScript 3.0 :: Detect A HitTest With The Cursor?

The current problem is trying to detect a hitTest with the cursor. I use this code very successfully in AS2, when I cannot use an rollover for whatever reason.

This is my AS2 code:

PHP Code:

onEnterFrame = function(){   if(my_mc.hitTest(_root._xmouse, _root._ymouse))   {      race("the mouse is positioned over my_mc")    }} 

This is me trying unsuccessfully to convert it to AS3:

PHP Code:

stage.addEventListener(Event.ENTER_FRAME, intro); function intro(e:Event):void{     my_mc.hitTest(mouseX, mouseY)     {        trace("the mouse is positioned over my_mc")     }}
