rewards for spawned undead/infected civs?

[der.hannes 10]

in my mission i get money rewards for each killed undead, i done this with a trigger:

present-guer

Cond: this

Act: {_x addeventhandler ["killed",{if(_this select 1 == player) then {[player] exec "scripts\Money_Shot.sqs"}}]} foreach thislist

this works fine for editor placed infected, but spawned units from undead-spawnmodule and people who got infected are not counting.

do i have to add the spawned undead to guerilla side? how?

found a command for checking the unittype (istype or so), i think i could just ask wheter a zombie-unit got killed by player - but i dont know how to realise this.

sorry for my noob questions but scripting is to hard for me and biwiki dont help me much...
