Access of undefined property- but its defined.

Question

I get that error message for all lines of choosetext()- which is referred every time I change the value of mode.

Answer 1

Try to define m22,m33...m99 as class variable, not in the boxsprite function

public class boxsprite extends Sprite  
{     

   private var m22:Bitmap;

   public function boxsprite():void {

      m22= new m2 as Bitmap;

   }



}
