Problem with my leaderboard?

This script is supposed to give the player to killed another player 3 money, and 1 kill. But when I kill someone else, it doesn't work. It also don't get any errors. Help?

game.Players.PlayerAdded:connect(function(player)
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local money = Instance.new("IntValue")
    money.Name = "Money"
    money.Value = 0
    money.Parent = leaderstats

    local kills = Instance.new("IntValue")
    kills.Name = "Kills"
    kills.Value = 0
    kills.Parent = leaderstats

    local level = Instance.new("IntValue")
    level.Name = "Level"
    level.Value = 1
    level.Parent = leaderstats

    game.Players.PlayerAdded:connect(function(player)
        player.CharacterAdded:connect(function(character)
            character.Humanoid.Died:connect(function()
                local killer = character.Humanoid:findFirstChild("creator")
                if killer then
                    killer.leaderstats.Kills.Value = killer.Value.Kills.Value + 1
                    killer.leaderstats.Money.Value = killer.leaderstats.Money.Value + 3
                end
            end)
        end)
    end)
end)

You're using the PlayerAdded event twice. The second one isn't loading. Additionally, this should be in a severscript if it isn't already.

game.Players.PlayerAdded:connect(function(player)
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local money = Instance.new("IntValue")
    money.Name = "Money"
    money.Value = 0
    money.Parent = leaderstats

    local kills = Instance.new("IntValue")
    kills.Name = "Kills"
    kills.Value = 0
    kills.Parent = leaderstats

    local level = Instance.new("IntValue")
    level.Name = "Level"
    level.Value = 1
    level.Parent = leaderstats

        player.CharacterAdded:connect(function(character)
            character.Humanoid.Died:connect(function()
                local killer = character.Humanoid:findFirstChild("creator")
                if killer then
                    killer.leaderstats.Kills.Value = killer.Value.Kills.Value + 1
                    killer.leaderstats.Money.Value = killer.leaderstats.Money.Value + 3
                end
            end)
        end)
    end)
