Gold stays at 10 only and i cant find the problem?

local datastore = game:GetService("DataStoreService"):GetDataStore("MyRPGDataStore")


game.Players.PlayerAdded:connect(function(player)
    local leaderstats = Instance.new("IntValue")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local xd = Instance.new("IntConstrainedValue")
    xd.Name = "Level"
    xd.Parent = leaderstats
    xd.Value = 1
    xd.MaxValue = workspace:FindFirstChild("GameSettings").MaxLevel.Value
    xd.MinValue = 0

    local qe = Instance.new("IntConstrainedValue")
    qe.Name = "EXP"
    qe.Parent = leaderstats
    qe.Value = 0
    xd.MaxValue = workspace:FindFirstChild("GameSettings").MaxEXP.Value
    xd.MinValue = 0

    local ss = Instance.new("IntConstrainedValue")
    ss.Name = "Gold"
    ss.Parent = leaderstats
    ss.Value = 0
    xd.MaxValue = workspace:FindFirstChild("GameSettings").MaxGold.Value
    xd.MinValue = 0

    local key = "user-" .. player.userId

    local storeditems = datastore:GetAsync(key)
    if storeditems then
        xd.Value = storeditems[1]
        qe.Value = storeditems[2]
        ss.Value = storeditems[3]
    else
        local items = {xd.Value, qe.Value, ss.Value}
        datastore:SetAsync(key, items)
    end

    while wait(120) do
        local stats = player:FindFirstChild("leaderstats")
        local aitems = {stats.Level.Value, stats.EXP.Value, stats.Gold.Value}
        local key = "user-" .. player.userId
    datastore:SetAsync(key, aitems)
    end
end)
