How do I make a GUI appear if I am on a certain team?[I SOLVED IT MYSELF]

Warden = game.Teams.Warden.TeamColor
Main = game.StarterGui["BOSS GUI"].Main
play = game.Players:getChildren()
function Warden()
for i = 1,#play do
    if play[i].TeamColor == game.Teams.Warden.TeamColor then
        Main.Visible = true
        else Main.Visible = false   
    end
end
end

Hi, thank you for reading.  I need help scripting on how to make a GUI appear if they are on the team called "Warden".  I've been trying to find out the problem but I just can't figure it out.  Can anyone help me?  Thank you.
