How do i display the Surface GUI leader board and how do i make a Rank from 1-10 Top player wins?

i already had this script

local ods = game:GetService("DataStoreService"):GetOrderedDataStore("WinsOrdered")
local ds = game:GetService("DataStoreService"):GetDataStore("Wins")
local lb = game:GetService("DataStoreService"):GetDataStore("LeaderBoard")

function UpdateBoard()
local leaderboard = ods:GetSortedAsync(false,10,nil,nil)
local lb = game.Workspace.Leaderboard.Board
local data = leaderboard:GetCurrentPage()

local currentlyOn = 0

for k,v in pairs(data) do
	wait()
	if k ~= nil and v ~= nil then
		currentlyOn = currentlyOn + 1
		local gui = lb.SurfaceGui.Example:clone()
		gui.Parent = lb
		gui.NameFrame.Label.Text = v.key
		gui.Number.Label.Text = v.value
		gui.Position = UDim2.new(0,0,0,65*(currentlyOn-1))
		gui.Visible = true
		gui.Parent = lb
	end
end
end

game.Players.PlayerAdded:connect(function(player)
	repeat wait() until player.Character ~= nil
	local wins = Instance.new("IntValue" , player)
	wins.Name = "Wins"
	wins.Value = ds:GetAsync("user_"..player.userId) or 0
	if wins.Value == 0 then
		ds:SetAsync("user_"..player.userId,0)
		ods:IncrementAsync(player.Name, 0)
	end
	wins.Changed:connect(function(v)ddddddddd
		ds:SetAsync("user_"..player.userId,v)
		ods:IncrementAsync(player.Name, wins.Value)
	end)
end)

while true do
	wait(10)
	UpdateBoard()
end

Its saying that "Board is not a value member of Script"
