Shooting game

1

I’ve been trying to follow a tutorial for a simple shooting game on http://www.video-animation.com/flash_12.shtml but was unable to get the “bullet” to replicate and shoot while i click. The only thing that happens is it launches one bullet when i test it but nothing else, has anyone else experienced this? I’m pretty sure I followed all the directions and copy/pasted the code into the actions area. Am i supposed to paste the the code to somehting other than the movie clips?
