Scripts

Hi! So, I previously asked about creating a counter for killed creatures, and I have this script:

function Duncan_Revenge( combatIndex )
    if GetSavedCombatArmyHero( combatIndex, 1 ) == "Duncan" then
        if GetSavedCombatArmyCreaturesCount( combatIndex, 0, 112 ) >= 1 then
            n_stacks = GetSavedCombatArmyCreaturesCount( combatIndex, 0 );
            for i = 0,(n_stacks-1) do
            local revenge_target, count, died = GetSavedCombatArmyCreatureInfo( combatIndex, 0, i );
                if revenge_target == 112 and died >= 1 then
                   enemieskilledcounter = enemieskilledcounter + died;
                   ShowFlyingSign({GetMapDataPath().."Duncan_Counter.txt"; showcounter=enemieskilledcounter}, "Duncan", 1, 10)
                end
            end
        end
    end
end

The script works, but it's annoying that the message with the number of killed creatures is displayed multiple times. I understand that this is due to multiple stacks. Is it possible to modify the script so that the message is displayed only once, showing the total number of killed creatures?
