Scratch

OK, so this is just some experimenting before I actually start the game.  http://scratch.mit.edu/projects/xAIRGUITARISTx/2210142  I have an issue though.  The first bullet (if you see the script, you'll see that there are 10 bullets, they fire when the "bullet" variable equals such... w/e)  The first bullet doesn't show up when it fires the first time if you just have 10 ammo.  But if you have 20 ammo, it won't fire at 20 but it will at 10.  Is this just a glitch? HELP!
