Hey,  
A simple access from class question:

I have a dynamic text field on my stage, instance name: “lives\_txt”  
I want to populate this field from my Document class “Ball.as”

So in my Ball.as class I have tried: parent.lives\_txt.text = String (lives);  
where: public var lives:int = 3;

I get an error: access of possibily undefined property lives\_mc through a reference with static type flash.display:DisplayObjectContainer.

What am I doing wrong?

Thanks
