Movieclip following the mouse triggered by a Rollover/out EventListener

Hi

I'm trying to get a small label to follow the mouse when the mouse is over the button and stops following and moves to the side on rollOut. Which works/worked until I wanted another one of the buttons to do the same but with a different label. The first one carried on working but the second one just flashed. There weren't any errors in the window either.

Heres my code:

Actionscript Code:

waterOrton_btn.addEventListener(MouseEvent.ROLL_OVER,startFollowW);
waterOrton_btn.addEventListener(MouseEvent.ROLL_OUT,stopFollow);

aCampus_btn.addEventListener(MouseEvent.ROLL_OVER,startFollowC);
aCampus_btn.addEventListener(MouseEvent.ROLL_OUT,stopFollow);

//================FUNCTIONS===================;
var nLabel;
//================Label Functions=================


function startFollowW(e:MouseEvent):void
{
    nLabel = waterO_pl;
    stage.addEventListener(Event.ENTER_FRAME, followMouse);
}

function startFollowC(e:MouseEvent):void
{
    nLabel = campus_pl;
    stage.addEventListener(Event.ENTER_FRAME, followMouse);
}

function stopFollow(e:MouseEvent):void
{
    stage.removeEventListener(Event.ENTER_FRAME, followMouse);
    nLabel.x = -100;
}

function followMouse(e:Event):void
{
    nLabel.x = mouseX;
    nLabel.y = mouseY;
}

nLabel is a variable containing the name of the movieClip I want to follow the mouse.

Help needed please :confused:
