Saving leaderstats with datastoring not working?

I'm trying to store the data of the leaderstats DataStoreService. I'm not getting any errors but it is also not working. my code:

local ds = game:GetService("DataStoreService"):GetDataStore("SaveData") game.Players.PlayerAdded:Connect(function(plr) wait() local plrkey = "id_"..plr.userId local save1 = plr.leaderstats.Coins

local GetSaved = ds:GetAsync(plrkey)
if GetSaved then
	save1.Value = GetSaved[1]
	
else
	local NumberOfSaving = {save1.Value}
	ds:GetAsync(plrkey, NumberOfSaving)
end

end)

game.Players.PlayerRemoving:Connect(function(plr) ds:SetAsync("id_"..plr.userId, {plr.leaderstats.Cash.Value}) end)
