I have done some reading for the Data Store and I came up with this script...

local Store = game:GetService("DataStoreService"):GetDataStore("XP/LEVEL")

game.Players.PlayerAdded:connect(function (player)
	local playername = player.Name
	local stats = Instance.new("IntValue")
	stats.Name = "leaderstats"
	stats.Parent = player
	
	local xp = Instance.new("IntValue")
	local xpStats = Store:GetAsync(playername.."XP")
	xp.Name = "XP"
	xp.Value = xpStats or 0
	xp.Parent = stats
	
	local Level = Instance.new("IntValue")
	local xpLevel = Store:GetAsync(playername.."LEVEL")
	Level.Name = "Level"
	Level.Value = xpLevel or 1
	Level.Parent = stats
end)

game.Players.PlayerRemoving:connect(function (player)
	local playername = player.Name
	local XP = player.leaderstats:FindFirstChild("XP")
	Store:SetAsync(playername.."XP",XP.Value)
		
	local LEVEL = player.leaderstats:FindFirstChild("Level")
	Store:SetAsync(playername.."LEVEL", LEVEL.Value)
end)

It loads fine, there is no errors on the output.. But it doesn't want to save or load the value's. Did I do the "Store:GetAsync" and the Store:SetAsync" incorrectly?
