I'm trying to check if my frame is set to true?

I'm trying to check if my frame is set to true in visible and if it is set to true to wait 5 seconds before setting visible to false

script I tried using:

if script.Parent.Parent.TrainerGui == true then wait(5) script.Parent.Parent.TrainerGui = false end

if script.Parent.Parent.TrainerGui.Visible == true then 
wait(5) 
script.Parent.Parent.TrainerGui.Visible = false 
end

You were checking if trainergui exists and setting something that I can't understand. That means you forgot for the property Visible
