VIP Player Billboard wont work?

I'm sure I'm missing something, but I'm not sure what it is.....Here's what I have so far... If I take out the "MarketplaceService", the script works fine, but obviously gives it to everyone. Thanks.

game.Players.PlayerAdded:connect(onPlayerRespawned)
function onPlayerRespawned(newPlayer)
		wait(1)
     
    local allow = (
        game:GetService('MarketplaceService'):UserOwnsGamePassAsync(player.userId, 1234567) 
    )
 
    if allow then
		local gui=Instance.new("BillboardGui")
		gui.Parent=newPlayer.Character.Head
		gui.Adornee=newPlayer.Character.Head
		gui.Size=UDim2.new(3,0,4,0) 
		gui.StudsOffset=Vector3.new(0,1,0)
		local name=Instance.new("TextLabel")
		name.Parent = gui
		name.BackgroundTransparency = 1
		name.Text = "VIP"  
		name.Size = UDim2.new(1,0,1,0)
		name.Position=UDim2.new(0,0,-0.81,0)
		name.TextColor3=Color3.new(255,255,255)
		name.FontSize = "Size18"
		end
end
function onPlayerEntered(newPlayer)
	newPlayer.Changed:connect(function (property)
		if (property == "Character") then
			onPlayerRespawned(newPlayer)
		end
	end)
end

game.Players.PlayerAdded:connect(onPlayerEntered)
