Death Match system

[CraZy.FroG[B]]

hello, I want to make a death match system like the one that's in Pudge Wars. In case you haven't heard or tried Pudge Wars, the game starts like this; when the game starts, a window pops up for the host with several features that can be choosed, such as 20 kills = win or 50 kills = win etc.

I'm been trying to make the system myself, but it doesn't seem to work whatsoever. can anyone fill me in on what to do? or give me an template if possiple to make life easier for me?

thanks in advance.
