Attachmovie movement abnormal, collsion not working

  1. For the collision detection for front_walk_animation movie clip. If i dont attach it to the player movie clip the collision is working. After attaching to player movie clip it no longer work.

  2. When pressing the down button, there is something weird about the attached movie playings. Seems like it play through all my frames once and it stop. Is there anyway to solve the problem?

Can anyone guide me? Thanks in advance~
