I’m having a challenge getting an event listener to use the target of the click to trigger a method of a custom class… probably easier to show in this super stripped down version. Here’s the class:

```auto
 
package {
 import flash.display.*;
 public class MyClass extends MovieClip {
  public var newObject:MovieClip;
  
  public function MyClass(whichClass:Class, whereToAdd:Object):void {
    newObject = new whichClass();
    whereToAdd.addChild(newObject);
    newObject.x=200;
    newObject.y=200;
  }
  public function hello():void {
   trace("HELLO WORLD");
  }
 }
}
 

```

and here’s the fla (which has one movie clip in the library… a simple box with a class of “square”):

```auto
 
var mySquare:square = new square();
var myObject:MyClass = new MyClass(square, this);
myObject.hello(); // this traces "HELLO WORLD"
stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseHandler);
function mouseHandler(evt:Event):void {
 trace("clicked");
 evt.target.hello(); // this throws an error: "hello is not a function" instead of tracing "HELLO WORLD"
}

```

Any brains out there that can give some input?
