            SendClientMessageToAll(COLOR_GREEN,string);

      }

That section of code would mean if the killer had the pStreak multidimentional value of 18+ there amount of cash would be CURRENT AMOUNT * 1000 and if they had the pStreak of < 18 then it would be CURRENT AMOUNT + 1000. I think that's what you wanted anyway?
