Accessing a variable from a different class file

I have a very simple car game using three Class Files, Game.as, Car.as, Level.as.

The Game.as acts as the document class.
The Car.as simply contains all the cars movements.
The Level.as contains all of the things relevant to the level, the map etc.

The Way i have set up my .fla is so that the Level class doesnt get called until the 3rd frame. (Making use of an invisible box).

In my Game.as file i load in an XML file and store the results in string variables. for example ‘var titleText:String;’ This is so i can use different languages throughout my game, the problem is, in my actual game (frame 3, so working within the level class) i cannot access any of the string variables from the Game class. I need to be able to do this to set the “score text” to the correct language.

Is there a way i can do this easily?

Thanks
