Hi I’m creating a winnie the pooh colouring in game and I’m getting  
TypeError: Error #2007: Parameter listener must be non-null.  
at flash.events::EventDispatcher/addEventListener()  
at ColouringinGame\_fla::MainTimeline/frame1()

The Code on the main time line is

import flash.events.MouseEvent;

var myColor = 0xFFFFFF;

function getBlack(event:MouseEvent):void {  
myColor = 0x000000;  
}  
function getLightBlue(event:MouseEvent):void {  
myColor = 0x33CCFF;  
}  
function getDarkBlue(event:MouseEvent):void {  
myColor = 0x3300CC;  
}  
function getGrey(event:MouseEvent):void {  
myColor = 0x666666;  
}  
function getLightGreen(event:MouseEvent):void {  
myColor = 0x66CC66;  
}  
function getDarkGreen(event:MouseEvent):void {  
myColor = 0x003300;  
}  
function getBrown(event:MouseEvent):void {  
myColor = 0x663300;  
}  
function getOrange(event:MouseEvent):void {  
myColor = 0xFF9900;  
}  
function getPink(event:MouseEvent):void {  
myColor = 0xFF66FF;  
}  
function getSkin(event:MouseEvent):void {  
myColor = 0xFFCCCC;  
}  
function getPurple(event:MouseEvent):void {  
myColor = 0x6600CC;  
}  
function getRed(event:MouseEvent):void {  
myColor = 0xFF0000;  
}  
function getWhite(event:MouseEvent):void {  
myColor = 0xFFFFFF;  
}  
function getYellow(event:MouseEvent):void {  
myColor = 0xFFFF00;  
}

function moveBrush (event:Event) : void {  
this.brush.startDrag (true);  
Mouse.hide();  
}

this.addEventListener(Event.ENTER\_FRAME, moveBrush);

And the code on the brush is

function paint(obj:Object,myColor:Number):void {  
var newColor:ColorTransform = new ColorTransform();  
newColor.color = myColor;  
obj.transform.colorTransform = newColor;  
}

function colorMe(event:MouseEvent):void {  
this.paint(this.tip, event.target.root.myColor);  
}

```
mouseEnabled = false;
```
