Game Pass privileges help (onClick function)?

Hello. I am making a script where if you have the gamepass for the game then instead of the click going up by 1, it will go up by 3 instead. I can't currently test the script because I am not in my house. (My parents are out of town so I'm staying at my friends... using his computer which does not have ROBLOX Studio).

local pass = 182358984
local number = 0
local upgrade = 1

function Auth(player)
     return game:GetService("GamePassService"):PlayerHasPass(player, pass)
end

script.Parent.MouseButton1Click:connect(function()
     if Auth then
         local upgrade = 3
     end
     number = number + upgrade
     script.Parent.Parent.Number.Text = number
end)
