I’m working in Flash CS3. I’ve set my Document class named Main and in the constructor I create my own config class:

```auto
var config:Configuration = new Configuration();

```

and I set a variable named TEST:

```auto
config.TEST = "hello world";

```

When I trace the property on the main Timeline it succeeds, but when I’m doing the trace() from within a MovieClip on the Timeline, it failes with the following error:

```auto
1120: Access of undefined property config.

```

What am I doing wrong, or what is proper way to do this?
