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)
