Scripting global leaderboards (as in ranking leaderboards)?

I assume you would know what a global leaderboard is, but if you don't then it is a leaderboard(not a leaderboard that is given when the player joins at the top right corner), that shows ranks from 1 to lets say 5. It is based off of the player's stats or leaderboard (eg. points)

Okay so now the problem. Here is my script which should work. But it is a little glitchy and I don't know why.

Stat = "Points" -- just an example

local ods = game:GetService("DataStoreService"):GetOrderedDataStore(Stat) 
local Leaderboard = script.Parent
local Top5ScoreBoard = Leaderboard.Top5ScoreBoard

function updateBoard(board, data)
	for k,v in pairs(data) do
		local pos = k
		local id = v.key
		local score = v.value
		local nametextbox = board.SurfaceGui:FindFirstChild("Name" .. pos)
		nametextbox.Text = game.Players:GetNameFromUserIdAsync(id)
		local scoretextbox = board.SurfaceGui:FindFirstChild("Score" .. pos)
		scoretextbox.Text = score
	end	
end

while true do
	local pages = ods:GetSortedAsync(false, 5)
	local data = pages:GetCurrentPage() 
	updateBoard(Top5ScoreBoard, data)
	wait(60)
end

OKAY so this is referring to a surface gui that has 10 text labels, 5 for the names and 5 for the value of the currency/points.

The problem is it wont update the score and sometimes it wont even show. Very glitchy..
