How do I get a movie clip to follow the cursor?

Hi guys,

What I want:

Is a simple action where I have my company logo in the middle of the screen and it follows the cursor (not over the whole screen but within invisible borders).

What I use:

I have Flash Pro CS5, code is Actionscript 3.0 and my company logo has been converted to a movie clip.

What didn't work:

So I watched 2 different tutorials on how to do this and both didn't work.

With the first one I used this code:

function gradientOver(event:MouseEvent):void{

          logomc.visible=true;

          function reportStageMouse(event:MouseEvent):void{

                    var myStageX:Number=Math.round(event.stageX);

                    var myStageY:Number=Math.round(event.stageY);

                    var xTween:Tween=new Tween(logomc,"x", Strong.easeOut, logomc.x, myStageX, 1, true);

                    var yTween:Tween=new Tween(logomc,"y", Strong.easeOut, logomc.y, myStageY, 1, true);

          }

          stage.addEventListener(MouseEvent.MOUSE_MOVE,reportStageMouse);

}

function gradientOut(event:MouseEvent):void{

          logomc.visible=false;

}

function gradientClick(event:MouseEvent):void{

          logomc.visible=false;

}

gradient.addEventListener(MouseEvent.ROLL_OVER,gradientOver);

gradient.addEventListener(MouseEvent.ROLL_OUT,gradientOut);

gradient.addEventListener(MouseEvent.CLICK,gradientClick);

And with the second one I had to make a border by drawing an oval shape, turn it into a movie clip and put my logo inside of it. Then I used this code:

stage.addEventListener("mouseMove", arjun);

function arjun(e:MouseEvent):void

{

          var var1 = mouseY - followins.y;

          var var2 = mouseX - followins.x;

          var radiusR = Math.atan2(var1,var2);

          var degreeR = radiusR / (Math.PI / 180);

          followins.rotation = degreeR;

}
