Why won't this datastore work, nothing saves?

local DSService = game:GetService('DataStoreService'):GetDataStore('theweirdlolsavedata669')
game.Players.PlayerAdded:connect(function(plr)
    local uniquekey = 'id'..plr.userId
    local stuff = Instance.new("Folder", plr)
    stuff.Name = "stuff"
    local Invun = Instance.new('IntValue', stuff)
    Invun.Name = "Stat1"


    local GetSaved = DSService:GetAsync(uniquekey)
    if GetSaved then
        Invun.Value = GetSaved[1]
    else
        local NumbersForSaving = {Invun.Value}
        DSService:SetAsync(uniquekey, NumbersForSaving)

    end
end)

game.Players.PlayerRemoving:connect(function(plr)
    local uniquekey = 'id'..plr.userId
    local Savetable = {plr.stuff.Stat1}
    DSService:SetAsync(uniquekey, Savetable)



end)
