[ CASE CLOSED? ]

I have this datastore script but its not saving my data and I was wondering if its because im in studio?

local datastoreservice = game:GetService("DataStoreService")
local datastore = datastoreservice:GetDataStore("mydatastore")
game.Players.PlayerAdded:Connect(function(player)

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

    local Green = Instance.new("IntValue")
    Green.Name = "Green"
    Green.Parent = leaderstats
    Green.Value = datastore:GetAsync(player.UserId.."Green")

end)

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

    datastore:SetAsync(player.UserId.."Green", player.leaderstats.Green.Value)

end)
