Why Does My Data Store Come Out With No Error Messages?

I am trying to expand my coding knowledge by (attempting) to scripting a commonly used scripting feature, data stores. I have searched up data stores on the roblox dev hub and still come out with an un-working, no error message script. Help would be greatly appreciated.

Code:

local DataStoreService = game:GetService('DataStoreService')
local GoldCurrency = DataStoreService:GetDataStore('PlayersGold')

game.Players.PlayerAdded:Connect(function(player)
    local PlayerID = player.UserId
    local leaderstats = Instance.new("Folder")
    leaderstats.Name = 'leaderstats'
    leaderstats.Parent = player

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

    local success, currentExperience = pcall(function()
        return GoldCurrency:GetAsync(PlayerID)
    end)

    if success then
        Gold.Value = GoldCurrency
    else
        Gold.Value = 0
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    local PlayerID = player.UserId

    local success, err = pcall(function()
        GoldCurrency:SetAsync(PlayerID, player.leaderstats.Gold.Value)
    end)

    if success then
        print("It Worked!")
    else
        print(err)
    end
end)
