I need help with making a working teleport Gui that takes you from game to game?

I have tried a lot but I still cant get a working Teleport GUI, and by that I mean one that teleports you to different places. Here is what I tried

local TeleportService = game:GetService("TeleportService")
local gameID = 1559604744


script.Parent.MouseButton1Click:connect(function()
	print("HI")
	if player then
        TeleportService:Teleport(gameID, player)
end)

please help me and thanks

Hello, turbomegapower12345!

I know why your script isn't working, It must be a Local Script and must have a variable that reffers to player!

Example of working one:

local TeleportService = game:GetService("TeleportService")
local gameID = 1559604744
local player = game.Players.LocalPlayer


script.Parent.MouseButton1Click:connect(function()
	if player then
        	TeleportService:Teleport(gameID, player)
	end
end)

This don't will teleport if you're in studio, must be a server!

Good Luck with your games!
