How to add "while true do" function among the KO WO point leaderboard?

I want to add a script where every 3 seconds, a point is added. The script works in build mode but not in the play mode when it's saved. Or even in some cases, the points work but the KO and WO doesn't work.

Is there a way to have the KO, WO and points script (that changes every 3 seconds) work at the same time?

Below is the script:

function onHumanoidDied(humanoid, player)
	local stats = player:findFirstChild("leaderstats")
	if stats ~= nil then
		local deaths = stats:findFirstChild("Deaths")
		deaths.Value = deaths.Value + 1
		local spend = stats:findFirstChild("Points")
		spend.Value = spend.Value - 5
	-- do short dance to try and find the killer
		local killer = getKillerOfHumanoidIfStillInGame(humanoid)
		handleKillCount(humanoid, player)
	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
			humanoid.Died:connect(function() onHumanoidDied(h, p) 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("KOs")
			local earn = stats:findFirstChild("Points")
			if killer ~= player then
				kills.Value = kills.Value + 1
				earn.Value = earn.Value + 100		
			else
				kills.Value = kills.Value - 1
				earn.Value = earn.Value - 1
				
			end
		end
	end
end

function Entered(player)
      if player:findFirstChild("leaderstats") ~= nil then
			player.leaderstats:remove()
      end

      stats = Instance.new("IntValue")
      stats.Parent = player
      stats.Name = "leaderstats"

		local kills = Instance.new("IntValue")
		kills.Name = "KOs"
		kills.Value = 0

		local deaths = Instance.new("IntValue")
		deaths.Name = "Deaths"
		deaths.Value = 0

		kills.Parent = stats
		deaths.Parent = stats

      money = Instance.new("IntValue")
      money.Parent = stats
      money.Name = "Points"
      money.Value = 0 --How much you start out with change it to how much you want

		-- VERY UGLY HACK
		-- Will this leak threads?
		-- Is the problem even what I think it is (player arrived before character)?
		while true do
			if player.Character ~= nil then break end
			wait(5)
		end

		local humanoid = player.Character.Humanoid

		humanoid.Died:connect(function() onHumanoidDied(humanoid, player) end )

		-- start to listen for new humanoid
		player.Changed:connect(function(property) onPlayerRespawn(property, player) end )


		stats.Parent = player

end


game.Players.PlayerAdded:connect(Entered)

c = game.Players:GetChildren()
for i=1, #c do
        Entered(c[i])
end


while true do
	wait(3)
	money.Value = money.Value + 1
	end

Thank you!
