Why won't the stats save?

I'm trying to save the points and points per second for my player point clicker game but it isn't working and I have no idea why. Can someone please help?

local pointStore = game:GetService("DataStoreService"):GetDataStore("playurData")
local playurData = {}

function ledurburd(playur)

local ledurstatts = Instance.new("Model", playur)
ledurstatts.Name = "leaderstats"

local yourData = pointStore:GetAsync(playur.userId) or {}
yourData.pp = yourData.Points or 0
yourData.ppPerSec = yourData.ppPerSec or 0  

playurData[playur.userId] = yourData

local pp = Instance.new("IntValue", ledurstatts)
pp.Name = "Points"
pp.Value = yourData.pp

local ppPerSec = Instance.new("IntValue", playur)
ppPerSec.Name = "PointsPerSecond"
ppPerSec.Value = yourData.ppPerSec

end

game.Players.PlayerAdded:connect(ledurburd)

function permaSave(playur)
if playur then
local yourData = playurData[playur.userId]
if yourData then
pointStore:SetAsync(playur.userId, yourData)
end
end
end

game.Players.PlayerRemoving:connect(function(playur)
if playur then
permaSave(playur)
playurData[playur.userId] = nil 
end
end)

game.OnClose = function()
for i,v in pairs(playurData) do
pointStore:SetAsync(i, v)
end
end
