Datastores are not working properly?

Hi,

I've recently started using DataStoreService for the first time, and wanted to implement them into my game to store users' Credits. It doesn't seem to error anywhere else, but it fails to get the player's data when they join the game.

Here's my code:

local DSS = game:GetService("DataStoreService")
local playerCreditScore = DSS:GetDataStore("playerCreditScore")

game.Players.PlayerAdded:Connect(function(Player)
    local leaderstats = Instance.new("Model")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = Player
    local Credits = Instance.new("IntValue")
    Credits.Name = "Credits"
    Credits.Parent = leaderstats

    local function getCredit()
        return playerCreditScore:GetAsync(Player.UserID)
    end

    local success, credit = pcall(getCredit)

    if success then
        Credits.Value = credit
    else
        warn("Could not get ", Player.Name,"'s credits.")
    end

end)

game.Players.PlayerRemoving:Connect(function(Player)
    local success = pcall(function()
        playerCreditScore:SetAsync(Player.UserId, Player.leaderstats.Credits.Value)
    end)
    if success then
        print("Successfully saved ", Player.Name,"'s credits.")
    else
        warn("Could not save ", Player.Name,"'s credits.")
    end
end)

FYI, the game has Filtering Enabled enabled.

Thanks
