I'm new to action script 3.0 programming and I'm learning about the Display List and running into compile errors and I can't figure out what I'm doing wrong. I continue to get the following errors:
1061: Call to a possibly undefined method getChildAt through a reference with static type flash.displayisplayObject.
1119: Access of possibly undefined property numChildren through a reference with static type flash.displayisplayObject.
isplayObject.
