leaderboard kills broken?

I got a tycoon kit which came with a leaderboard but the kills dont work, how can I fix this?

local Settings = require(script.Parent.Settings)
script.Parent = game.ServerScriptService
stands = {}
CTF_mode = false

function onHumanoidDied(humanoid, player)
	local stats = player:findFirstChild("leaderstats")
	if stats ~= nil then
		local deaths = stats:findFirstChild(Settings.LeaderboardSettings.DeathsName)
		if deaths then
			deaths.Value = deaths.Value + 1
		end
		-- do short dance to try and find the killer
		if Settings.LeaderboardSettings.KOs then
			local killer = getKillerOfHumanoidIfStillInGame(humanoid)
			handleKillCount(humanoid, player)
		end
	end
end

function onPlayerRespawn(property, player)
	-- need to connect to new humanoid
	
	if property == "Character" and player.Character ~= nil then
		local humanoid = player.Character.Humanoid
		local p = player
		local h = humanoid
		if Settings.LeaderboardSettings.WOs then
			humanoid.Died:connect(function() onHumanoidDied(h, p) end )
		end
	end
end

function getKillerOfHumanoidIfStillInGame(humanoid)
	-- returns the player object that killed this humanoid
	-- returns nil if the killer is no longer in the game

	-- check for kill tag on humanoid - may be more than one - todo: deal with this
	local tag = humanoid:findFirstChild("creator")

	-- find player with name on tag
	if tag ~= nil then
		
		local killer = tag.Value
		if killer.Parent ~= nil then -- killer still in game
			return killer
		end
	end

	return nil
end

function handleKillCount(humanoid, player)
	local killer = getKillerOfHumanoidIfStillInGame(humanoid)
	if killer ~= nil then
		local stats = killer:findFirstChild("leaderstats")
		if stats ~= nil then
			local kills = stats:findFirstChild(Settings.LeaderboardSettings.KillsNames)
			if kills then
				if killer ~= player then
					kills.Value = kills.Value + 1	
				else
					kills.Value = kills.Value - 1
				end
			else
				return
			end
		end
	end
end
