Add a person who killed the Target special Score Points

[clawhammer 10]

Hello!

i know that i can use this command to give a player score points: http://community.bistudio.com/wiki/addScore

Now i want to make it that if a player (Multiplayer) kill the target person he becomes additional score.

How can i create such a Trigger?

Thanks for help!

UPDATE:

This comes into the unit that get killed in the init field:

_index = VIP01 addMPEventHandler [""mpkilled"", {Null = _this execVM ""Scripts\VIP\VIP.sqf"";}];

Code of the VIP.sqf:

Hint "Test";

Killer = _this select 1;

if (isServer) then {
Killer addScore 100; // for hosted environment
} else {
paddscore = [Killer, 100]; publicVariable "paddscore";
};

It works but it has one mistake, i dont get just 100 Points!

I get 200 Points and i have no clue why!?

I belive it has something to do with the player on the server, if there are more the script gets executed at every player.

Any idea how to fix this?
