Bullet Hittests

First off thanks to people like Joman and Signifer123 who helped me get this far on my first game.:thumb:

  Okay here it is, I ran into a problem with "killing" the enemies, The first shot that is automatically fired will remove the enemy but if I move the enemy movieclip out of the range of the first shot the later shots do not affect it. Any ideas why it does this? I would post the code but I think its getting to complicated but here are the fla. files.
