GUI visible when player is seated in specific chair?

How would I go about doing this? This is what I have so far:

local seat = workspace.FaceChairs.Chair.Seat
local player = game.Players.LocalPlayer
local gui = player.PlayerGui.FaceGui.Frame

	if seat.Occupant == player.Character.Humanoid then
		gui.Visible = true
	else
		if seat.Occupant == nil then
			gui.Visible = false
	end
end
