A script that play a music in a game?

So I made a GUI and put this script in it.

local okbutton = script.Parent.TextButton

function onClicked(id)
	id = script.Parent.TextBox.Text
	local music1 = Instance.new("Sound")

	music1.Parent = game.Workspace

	music1.SoundId = "http://www.roblox.com/asset/?id="..id

	wait(1)
	music1:Play()
end

script.Parent.TextButton.MouseButton1Click:Connect(onClicked)

Well, it's not working. Can somebody help me fix this?

I tested my script out and I found out that it works!

local okbutton = script.Parent.TextButton
okbutton.MouseButton1Click:Connect(function()
	local id = script.Parent.TextBox.Text
	local music1 = Instance.new("Sound")

	music1.Parent = game.Workspace

	music1.SoundId = "rbxassetid://"..id

	wait(1)
	music1:Play()
end)
