The DataStore in my script is not saveing why?

Hi. am trying to use Data Store for the first time. Am having a hard time figuring out why this script dos not save my leaderstats when leaving a local test.. This script is not in a local script and I've unchecked the API box in game configuration. Any help would be appreciated :).

Da code:

local DS = game:GetService("DataStoreService")
local Players = game:GetService("Players")
local DSStats = DS:GetDataStore("Stats")
--local datastore = DS:GetDataStore("PlayerStats")

game.Players.PlayerAdded:connect(function(player)
	--player:WaitForDataReady() -- make sure we aren't looking for leaderstats before they are created
	--wait(2) -- just in case
	
	--creating leaderstats
	local leaderstats = Instance.new("Folder",player)
	leaderstats.Name = "leaderstats"
	local goldstats = Instance.new("IntValue",leaderstats)
	goldstats.Name = "Gold"
	------------------------
	

	local data = DSStats:GetAsync(tostring(player.UserId))
	if data==nil then
		print("data is nil")
		return
	end
	---exstract data
	local PlayerStats = player:FindFirstChild("leaderstats"):GetChildren()
	for i=1,#PlayerStats do
		PlayerStats[i].Value=data[PlayerStats[i].Name] or 0
		print(PlayerStats[i])
	end
end)

game.Players.PlayerRemoving:connect(function(player)
	local Data={}
	local PlayerStats = player:FindFirstChild("leaderstats"):GetChildren()
	for i = 1, #PlayerStats do -- creates a loop for all the stats
		Data[PlayerStats[i].Name]=PlayerStats[i].Value
		print(PlayerStats[i].Value)
	end
	DSStats:SetAsync(tostring(player.UserId), Data)
end)

(script is in ServerScriptService)
