Value not showing up on Global Leaderboard?

This is what i can come up with, what is the problem it will not show the value witch is "KOs"? I made my leaderstats datastored if that might help with the problem.

local DataStore = Game:GetService("DataStoreService"):GetOrderedDataStore("KOs")
local Pages = DataStore:GetSortedAsync(false, 10)
local List = Pages:GetCurrentPage()

function Update()
    for k,v in pairs(List) do
        TextLabel1 = Game.Workspace.Global.Board.SurfaceGui:FindFirstChild("Name"..k)
        TextLabel1.Text = v.key
        TextLabel2 = Game.Workspace.Global.Board.SurfaceGui:FindFirstChild("Score"..k)
        TextLabel2.Text = v.value
    end     
end

while true do wait()
    Update(List)
end

THIS IS SUPPOSE TO RANK THE PLAYERS BY HOW MUCH KOS THEY HAVE FROM 1-10
