How i can insert a "Diamonds" in Leaderstats?

(Sorry for bad english)

Hi guys! Another simple request but i'm very bad with Lua... I need to insert another currency called "Diamonds", but.. if i try to insert the currency, not appear in game... This is the script without the diamonds currency ->

-- local diamondsName = "Diamonds"
local serverStorage = game:GetService("ServerStorage")
local currencyName = "Money"
local DataStore = game:GetService("DataStoreService"):GetDataStore("ProvaDataStore")

game.Players.PlayerAdded:Connect(function(player)

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

    local currency = Instance.new("IntValue")
    currency.Name = currencyName
    currency.Parent = folder

    local ID = currencyName.."-"..player.UserId
    local savedData = nil   

    pcall(function()
        savedData = DataStore:GetAsync(ID)
    end)

    if savedData ~= nil then
        currency.Value = savedData
        print("Data loaded")
    else
        currency.Value = 10
    end

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

    local power = Instance.new("NumberValue")
    power.Name = "Power"
    power.Parent = leaderstats

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

    local dataFolder = Instance.new("Folder")
    dataFolder.Name = player.Name
    dataFolder.Parent = serverStorage.RemoteData

    local debounce = Instance.new("BoolValue")
    debounce.Name = "Debounce"
    debounce.Parent = dataFolder

end)

Thanks!
