How to give Cash when I killed an actual player?

I have a script within my NPC that correctly gives cash to the player when the player kills the NPC. I had to insert a script within the NPC to call a remote event, but I'm not quite sure how to do that with an actual player. I need to give 10 cash when a player kills another player. What am I doing wrong here? (FYI this is inside my save data, hence the other stuff in there.)

Look at lines 25-32. That is where I am checking if the player died to give money to whoever killed them.

local function onPlayerAdded(player)
    local playerKey = "Player_" .. player.UserId
    wait()
    print("User ".. player.UserId.. " Joined")

    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local Cash = Instance.new("IntValue")
    Cash.Name = "Cash"
    Cash.Parent = leaderstats

    local myCash
    local success, err = pcall(function()
          myCash = CashStore:GetAsync(playerKey) or STARTING_CASH
    end)
    if success then
        Cash.Value = myCash
        print("loading "..myCash)
    else
        print("failed to retrieve data")
        warn(err)
    end

    player.CharacterAdded:Connect(function(Character)
        Character.Humanoid.Died:Connect(function(Died)
            local creator = Character.Humanoid:FindFirstChild("creator")
            local leaderstats = creator.Value:FindFirstChild("leaderstats")
            if creator ~= nil and creator.Value ~= nil then
                leaderstats.Cash.Value = leaderstats.Cash.Value + 10
            end
        end)
    end)

    game.ServerStorage.Give.Event:Connect(function(Amount)
        wait()
        Cash.Value = Cash.Value + Amount
    end)

end
game.Players.PlayerAdded:Connect(onPlayerAdded)
