	-- Define variables
	local UniqueKey = 'id-'..plr.userId
	
	local PlayerStats = Instance.new('Folder', plr)

		SaveValue.Value = GetSaved[1]
	else
		local NumbersForSaving = {SaveValue.Value}
		DSService:SetAsync(UniqueKey, NumbersForSaving)
	end
end)

game.Players.PlayerRemoving:connect(function(plr)
	
	local UniqueKey = 'id-'..plr.userId
	
	local Savetable = {plr.PlayerStats.Cash.Value}
	DSService:SetAsync(UniqueKey, Savetable)	
end)

The script broken or something so the error is

508: Exhausted all retries for key: %s HTTP 0 (HTTP 403)

Script 'ServerScriptService.DataStore', Line 15
