I am making this game and a script in my game is encountering errors, How do I fix this? [closed]

So, I was just trying to make a kill for money script for my game, I keep on encountering errors whenever I try using the code that I provided.

Here is the code I used

game.Players.PlayerAdded:connect(function(player)
    local folder = Instance.new("Folder",player)
    folder.Name = "leaderstats"
    local currency1 = Instance.new("IntValue",folder)
    currency1.name = "Cash"
    player.CharacterAdded:connect(function(character)
        character:WaitForChild("Humanoid").Died:connect(function()
            local tag = character.Humanoid:FindFirstChild("creator")
            if tag ~= nil then
                if tag.Value ~= nil then
                    local stats = tag.Value:WaitForChild("leaderstats")
                    stats["Cash"].Value = stats["Cash"].Value + 10
                end
            end
        end)
    end)
end)

Whenever I try killing an NPC or person, it just doesn't work. Can someone please help me?
