How Can I Make My GUI Wait Before It's Visible?

Im not too bad at debugging code but im horrible at wrighting it so pls correct me if im wrong:

you have put a dot next to the 1 like so:

local player = game.Players.LocalPlayer
local gui = player.PlayerGui
function Touch()
    gui:findFirstChild("SonicTeam").Main.Visible = true
    ***wait(.1)***
    gui:findFirstChild("TeamSelect").Main.Visible = false
end

script.Parent.MouseButton1Down:connect(Touch) 

The bolded bit and italic is where 1 of your errors are. The computer cannot halt its self for a tenth of a second, i must be between 1 second and infinity seconds as it counts time in seconds so I suggest doing:

local player = game.Players.LocalPlayer
local gui = player.PlayerGui
function Touch()
    gui:findFirstChild("SonicTeam").Main.Visible = true
    wait(2-3)
    gui:findFirstChild("TeamSelect").Main.Visible = false
end

script.Parent.MouseButton1Down:connect(Touch) 

Then you have it, the rest are hidden to me so try that. if that works or do 1 second where i put the minus 1. That is if you have included a calculator in yours. xD
