I want to make a frame visible when you sit on a seat, why wont my script work?

I've made about 3 questions on this, NONE of the answers worked, please help. client not server

	Seat:GetPropertyChangedSignal("Occupant"):Connect(function()
	    if Seat.Occupant == nil then 
	        frame.Visible = false
	        return
	    end
	    frame.Visible = true
	wait(1)
	frame.Visible = false
	end)
