Como faço para limitar o tempo de gravação?

Ola boa noite,

Eu sou totalmente iniciante em Flash / Action Script e estou com um problema para resolver e acredito que aqui eu encontre a solução.

Estou precisando limitar o tempo da gravação do usuário tipo para 1 minuto, porém ja tentei limitar com nTimer = setInterval(stopRecording, 60000); dentro actionscript exemplo da Adobe, mas não esta funcionandoi. Ja fui no site da Adobe e mesmo assim não consegui compreender onde esta o erro.

Estou postando abaixo o Action da Adobe que esta funcionando perfeitamente, oq ue eu realmente gostaria era apenas limitar o tempo da gravação.

Agradeço muito se alguém puder me ajudar.
