Surface GUI Universe Teleport Button Help?

I have tried tons of scripts but none will work for my SurfaceGUI on a simple part. I click it and nothing happens, nothing in the output too. I want it to teleport to a place in my game universe. Here is the code I've tried recently.

function onClicked(playerWhoClicked)
    local player = game.Players[playerWhoClicked]
    if player then
        game:GetService("TeleportService"):Teleport(512970811, player)
    end
end

script.Parent.Button1Down:connect(function(playerWhoClicked)
	local player = game.Players[playerWhoClicked]
	if player then
		game.GetService("TeleportService"):Teleport(512970811,player)
	end
end)

This script assumes that the script is in the button
