Why does my datastore script not save anything?

I want to save the players data in a table and I want it to save when the player leaves the game (I will add save interval later). I set the table value to the value in the players leaderstats which I change when testing in studio. When I do so and print the value it says 0 instead of the number I changed the value to. I get no errors.

local DSS = game:GetService("DataStoreService")
local playerStore = DSS:GetDataStore("PlayerData")
local saveInterval = 10
local PlayerData = {Gold=0,Kills=0}

game:GetService("Players").PlayerAdded:Connect(function(plr)
	local UID = plr.UserId
		
	local stats = Instance.new("Folder")
	stats.Parent = plr
	stats.Name = "leaderstats"
	
	local gold = Instance.new("IntValue")
	gold.Parent = stats 
	gold.Name = "Gold"
	
	local kills = Instance.new("IntValue")
	kills.Parent = stats
	kills.Name = "Kills"
	
	local success, data = pcall(function()
		return playerStore:GetAsync(UID) or PlayerData
	end)
	
	if success then
		for k,v in next, data do
			if k == "Gold" then
				gold.Value = v
			elseif k == "Kills" then
				kills.Value = v
			end
			print(k,": ",v)
		end
	end
	
	-- Save data when player leaves
	game.Players.PlayerRemoving:Connect(function()
		PlayerData.Gold = gold.Value 
		PlayerData.Kills = kills.Value
		
		print(PlayerData.Gold) -- Prints 0?
		print(PlayerData.Kills) -- Prints 0?
		
		local success, err = pcall(function()
			playerStore:SetAsync(UID,PlayerData)
		end)
		
		if not success then 
			warn("Database Error: "..err)
		end
	end)
end)

Hi. This is code to make a datastore. In your case, just pack your two values into a table to save it when the player leaves, then unpack it again when they join. https://pastebin.com/2Z3X6USG
