Needs help to create two leader stats value?

Needs help to crate two leader stats value for example: Stage value and Points Value? my script just showing Stage Value.I hope to edit my script because I am not good at English: Note: this script auto saving players data

local DataStore = game:GetService("DataStoreService")
local ds = DataStore:GetDataStore("StageSaveSystem")

game.Players.PlayerAdded:connect(function(player)
 local leader = Instance.new("Folder",player)
 leader.Name = "leaderstats"
 local Stage = Instance.new("IntValue",leader)
 Stage.Name = "Stage"
 Stage.Value = ds:GetAsync(player.UserId) or 0
 ds:SetAsync(player.UserId, Stage.Value)
 Stage.Changed:connect(function()
  ds:SetAsync(player.UserId, Stage.Value)
 end)
end)


game.Players.PlayerRemoving:connect(function(player)
 ds:SetAsync(player.UserId, player.leaderstats.Stage.Value)
end)
