hey there folks,

need a little hand, i am trying to activate a function within a class on a mouse rollover -this is AS2 in CS3 and i have the following in my Class.as:

```php

private function mouseEvents(new_pane, pane_name)
 {
  new_pane[pane_name].onRollOver = function () 
  {
   movePanes()
   this._alpha = 50
  }
  new_pane[pane_name].onRollOut = function () 
  {
   this._alpha = 100
  }
 
 }
 
 public function movePanes():Void
 {
  var i:Number
  for(i in _global.pane_array)
  {
   trace(_global.pane_array*)
  }
 }

```

the global.pane\_array is specified in my FLA  
Obviously i would like to see the trace from the array, but nada…  
if i put the movePanes() outside the rollover event, it works fine… however this does not achieve my goals

also if i declare the function as a global function from within my FLA, and then call it on the rollover e.g. \_global.movePanes() - it works!

I could really use some assistance here as have an imminent deadline approaching…

Many Thanks
