How do you make a kill streak trigger!

[pikachux4]

I need help making a kill streak trigger. Like if a unit kills another units 2 times without "dying" then it would say owner of the unit[killer] got double kill! and so on. I needs a full example trigger thanks I am going to modify it so it works with my map.

• Kill Streak
  • Events
    • Unit - A unit Dies
  • Conditions
  • Actions
    • Set PlayerKillStreakVar[(Player number of (Owner of (Triggering unit)))] = 0
    • Set PlayerKillStreakVar[(Player number of (Owner of (Killing unit)))] = (PlayerKillStreakVar[(Player number of (Owner of (Killing unit)))] + 1)
      • Multiple FunctionsIf (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • PlayerKillStreakVar[(Player number of (Owner of (Killing unit)))] Equal to (==) 2
        • Then - Actions
          • Custom script: Double Kill!
        • Else - Actions
    • Custom script: Etc.

EDIT: whoops forgot to add the part about not dying... hold up
EDIT: done, this trigger works only if each player has only one unit that can die. PlayerKillSteakVar is a Integer Array with 12 slots
