Hello Lee, Yes I did, if you mean by using the statement
import mx.containers.*; I think the problem is that the getChildAt() method returns a DisplayObject, but I don't know how to cast it as an HBox or any other UIComponent. The DisplayObject doesn't even have a getChildAt() method. If I could figure out how to cast the returned DisplayObject as a particular UI component that would be great.
