Teleport to spawn button only working in the Roblox editor. But not when published to Roblox?

Hello, I made this script that is supposed to teleport the player to spawn when the player clicks on a button. I set it up in StarterGui, then I created a billboardgui, and then a text button. it works when I click on the play in the Roblox editor, but when I publish it to Roblox, it does not work.

countdown = 7



local i = 1
spawn2 = game.Workspace.SpawnLocation
time2 = 7
player = script.Parent.Parent.Parent.Parent
player2 = game.Players.LocalPlayer.Name

function onClicked()
	if script.Parent.Text == ("Teleport to Spawn") then
	for i = countdown,1, -1 do  	
		script.Parent.Text = (i)
		wait(1)
	end
	script.Parent.Text = ("Teleport to Spawn")
		player.Character:MoveTo(spawn2.Position)
		local h = game.Workspace:findFirstChild(player2):findFirstChild("ForceField")
	if h~=nil then
		h:remove()
			end
		end
	end
script.Parent.MouseButton1Down:connect(onClicked)
