First Post! I like what you’ve done with the place.

```
                     I'm was getting good with as2 but recently made the mind switch from, I'll learn as3 tomorrow to as3 is awesome. The problem for me is that I don't understand the scope for classes. I know I can trace a variable on the main time line when the var is declared in the class. But how do you access a main time line var from a class?

```

Here’s an example - main time line Monkey.fla

```auto
var cagedMonkies:int = 10;
var monkeyTransport:MovieClip = new CarTrunk();

```

Here’s the second part - CarTrunk.as

```auto
package {
       import flash.display.MovieClip;
    public class CarTrunk extends MovieClip {
      public function CarTrunk() {
        trace(cagedMonkies);
             }
    }
}

```

What would I need to change or do to make code like this work?
