Hey Guys,

I have created a movieclip in the library and added a class to it. I want to access a function and set an Array in that class from the document class…

Heres what im doing now which is not working… it says startnow function is undefined.

```php

package com {
 
 import flash.display.*;
 import flash.events.*;
 import com.NavMC
 
 public class Capability extends MovieClip {
  // Constants:
  // Public Properties:
  public var navMC:NavMC
  public var listMovies:Array = new Array("page1.swf","page1.swf","page1.swf")
  // Private Properties:
  // UI Elements:
 
  // Initialization:
  public function Capability() {
   navMC:NavMC= new NavMC()
   navMC.setArray = listMovies
   navMC.StartNow()
  } 
 }
}

```

Here is the class for the movieclip in the Library, the movieclip is already on the stage.

```php

package com {
 
 import flash.display.*;
 import flash.events.*;
 
 public class NavMC extends MovieClip {
  // Constants:
  // Public Properties:
  public var listMovies:Array = new Array();
  // Private Properties:
  // UI Elements:
 
  // Initialization:
  public function NavMC() {
  }
  public function set setArray(_listMovies:Array) {
   listMovies = _listMovies;
   trace ("setArray"+listMovies); // Does not trace
  }
  public function set StartNow() {
   //Start the code. // This does not work.
  }
 }
 
}

```

Im just a bit confused :puzzled:
