Help with simple game (removemovieclip)?

In the attached example, you can hopefully see the problem i’m having. When shooting the incoming rocket (to prevent it hitting the city), i’ve managed to get it to play the death animation properly, but not to remove it. On the crosshair, I have the code that should remove the movieclip when shot, but it’s not working. Any ideas?
