I am trying to shorten the code needed to be written for mcs on the stage. I followed the Help article about for() but i get an error saying “Access of undefined property nav.”

Any thoughts?

```auto

var i = 1

for (i=1; i<5; ++i) {
     nav+*.addEventListener(
          MouseEvent.MOUSE_UP,
          function(evt:MouseEvent):void {
        trace("I've been clicked!");
  }
);

}

```
