Help On error Please

Can anyone Help me with this error :

NullReferenceException: Object reference not set to an instance of an object Boo.Lang.Runtime.RuntimeServices.Dispatch (System.Object target, System.String cacheKeyName, System.Type[] cacheKeyTypes, System.Object[] args, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.Dispatch (System.Object target, System.String cacheKeyName, System.Object[] args, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory) Boo.Lang.Runtime.RuntimeServices.SetProperty (System.Object target, System.String name, System.Object value) ResPlaye1.Update () (at Assets/ResPlaye1.js:21)

here is the script:

  var spawnPlayer1 : Transform; //drag your spawn point to here in the inspector -    probably make it an empty gameobject so you can move it about on the diving board

     //var MainPlayerPlayer2: GameObject;

     var NewPlayerPrefab2 : Transform;

     var MainPlayer11 : GameObject;

      var MainCube : GameObject;

      var MainBodyTrue: GameObject;

      var MainHairTrue: GameObject;

       function Update()






            GetComponent(NewMoveScript).active = true; // This line is causing the problem ?


You probably forgot to assign one of your variables in your script.
