the animation sounds promising, but...
you sadly animated the whole thing outside from the main work-space (AKA=the small white square in the middle of the flash animating program).
therefore, we can only see the feet of the 2 madness characters, and their bullets, while the sounds also work properly...
so, the solution here is simple:
move all of your characters into the main work-space (AKA=the small white square in the middle of the flash animating program), specifically by ''selecting all'' the parts of the first frame, and then move them to the center of your main work space, until everything is inside the central white square of your animation.
if your characters cant fit at this square, then go to properties, and enlarge the main movie's size (width X height, in pixels).
i hope that i was helpful, because its sad to see a promising new animator having to encounter such mistakes in his first steps... :/
