[Resolvido]Não acesso o stage

Eai galera,

Pessoal.. to com um erro besta, ja tentei de mil e uma maneiras de acessar o stage mas nesse código não sei pq não funciona..

em qualquer parte do código ele me da o seguinte erro: TypeError: Error #1009: Cannot access a property or method of a null object reference.

mesmo se eu der somente um trace(stage.stageWidth);
