Why isn't this working? Doesn't give points when killing another player?

The idea of this script is to give me currency and experience points when I kill another player. However it isn't working.

local cv = c.Humanoid:findFirstChild("creator")
game.Players.PlayerAdded:connect(function(p)
	p.CharacterAdded:connect(function(c)
		c.Humanoid.Died:connect (function()
			if cv then local k = cv.Value if k and k ~= p then
				k.leaderstats.Experience.Value = k.leaderstats.Experience.Value + 100
				k.leaderstats.Currency.Value = k.leaderstats.Currency.Value + 50
		end)
	end)
end)

When you do local cv = c.Humanoid:findFirstChild("creator") the variable c doesn't exist at the time, meaning the script isn't able to find the localc. You would need to replace all the cv's with c.Humanoid:findFirstChild("creator") and then try it. However it still might not work as the script is quite messy.
