How to save data for a game (money)? Blah Blah

So I watched a vid and copied all the script exact, besides name of money. I ran it and it didn't work can someone correct the script.

local dataStores = game:GetService("DataStoreService"):GetDataStore("BuckDataStore")
local playerLeft = 0

game.Players.PlayerAdded:Connect(function(player)
	
	playerLeft = playerLeft + 1

	local stats = Instance.new("IntValue")
	stats.Name = "leaderstats"
	stats.Parent = player
	
	local money = Instance.new("IntValue")
	money.Name = "ObbyBucks<|>" -- Change "Money" to anything you want to name it like "Cash"
	money.Value = 100 -- Change the value to how many you want when the player joins the game
	money.Parent = stats
	
	player.CharacterAdded:Connect(function(character)
		character.Humanoid.Walkspeed = 16
		character.Humanoid.Died:Connect(function()
			if character.Humanoid and character.Humanoid:FindFirstChild('creator') then
				game.ReplicatedStorage.Status.Value = tostring(character.Humanoid.creator.Value.." Killed "..player.Name)
			end
			
			if character:FindFirstChild('GameTag') then
				character.GameTag:Destroy()
			end
			
			player:LoadCharacter()
		end)
	end)
	

	local player_data
	
	pcall(function()
		player_data = dataStores:GetAsync(player.UserId.."-ObbyBucks<|>")
	end)
	
	if player_data ~= nil then
		money.Value = player_data
	else
		money.Value = 100
	end
	
end)

local bindableEvent = Instance.new("BindableEvent")
	
game.Players.PlayerRemoving:Connect(function(player)
	pcall(function()
		dataStores:SetAsync(player.UserId..'-ObbyBucks<|>',player.stats.money.Value)
		print('Saved')
		playerLeft = playerLeft - 1
		bindableEvent:Fire()
	end)
end)

game:BindToClose(function()
	while playerLeft > 0 do
		bindableEvent.Event:Wait()
	end
end)
