help with dance gun!

[BANDIT2338 10]

hey i am really a noob when it comes to scripting but i would like to make a nice idea of mine real:P

i want a gun that when its fired makes the people dance.

like in the movie "rock that body"

i managed to make guys dance and i managed to create the weapon for it...

also trying to create a weapon which looks like the guns of the video

but what do i have to do to have this weapon make them dance instead of killing them?

when i reduced the damaged it didnt kill them but also didnt made anything else......

after the dance they should get killed^^

would be awesome if you guys could give me some tips^^
