I don’t understand why I am getting this error…

package Classes {  
public class HomePage extends Sprite {  
public function HomePage():void  
{  
buildLogo();  
}

public function buildXML():void  
{  
var xml:XML =  
\<navHolder\>  
\<nav id=“Blog”/\>  
\<nav id=“Store”/\>  
\<nav id=“Projects”/\>  
\<nav id=“Information”/\>  
\</navHolder\>;  
}  
public function buildLogo():void{  
color.color = 0x000000;  
LogoBg = drawSquare(200,150,0,0,color);  
LogoBg.x = 200;  
LogoBg.y = 200;  
addChild(LogoBg);  
}  
}}

I have more functions but I am having trouble with nested classes.  
Here is the code in the document class.

package Classes {  
import Classes.HomePage;  
private var c:Object = new HomePage();

public class BuildHome extends Sprite {

public function BuildHome():void  
{  
addChild(display);  
fillTheBoard();

```
    }

```

}  
}

When I use the buildXML function in my constructor, everything works fine. but when I try to use buildLogo it gives me this error…

TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at Classes::HomePage/buildLogo()  
at Classes::HomePage$iinit()  
at Classes::BuildHome$iinit()

could it be addChild without a reference since I assume that this nested class couldn’t access the stage? Or something like that… gurus help please 🙂

and thanks in advance.

this is a great forum!
