Why is this datastore not working? I'm trying to make a daily reward system.

So I'm trying to make a daily reward system for a game, and if the player gets any points any other way than the daily reward system, then those points don't save, only points from the daily reward.

local vipGamepassID
local marketPlaceService = game:GetService("MarketplaceService")
local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("DailyReward")

local dailyRewardWait = .002 -- hours put /3600 for seconds
local reward = {350, 1500} -- points

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder")
    leaderstats.Parent = player
    leaderstats.Name = 'leaderstats'
    
    
    local points = Instance.new("NumberValue")
    points.Value = 0
    points.Parent = player.leaderstats
    points.Name = 'Points'
    
    local userData
    pcall(function()
        userData = dataStore:GetAsync(player.UserId..'1')
    end)
    if userData then
        if (os.time() - userData.rewardWait) / 3600 >= dailyRewardWait then
            if player.Name == "ChillTart" then
                game.ServerStorage.VipDailyReward:Clone().Parent = player.PlayerGui
            userData = {points = userData.points + reward[2]; rewardWait = os.time();}
            else
                game.ServerStorage.DefaultDailyReward:Clone().Parent = player.PlayerGui
                userData = {points = userData.points + reward[1]; rewardWait = os.time();}
            end
        dataStore:SetAsync(player.UserId..'l', userData)
        end
        points.Value = userData.points
    else
    game.ServerStorage.NewPlayerNotification:Clone().Parent = player.PlayerGui
        dataStore:SetAsync(player.UserId..'l', {
            points = 0;
            rewardWait = os.time();
        })
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local saved, failed = pcall(function()
		dataStore:SetAsync(player.UserId..'l', player.leaderstats.Points.Value)
	end)
	
	if saved then
		print'saved'
	else
		print'datastore failed'
		print(failed)
	end
end)
