GUI Script not working?

I made a script that gives you a different GUI depending on the name of an object. However, the script only works if the object has the specified name, and doesn't give you any GUI if the name is different. Here is the script:

function loadscreen(Player)
	if script.Parent.Parent.Name == "TB" .. Player.Name then
	if not Player.PlayerGui:FindFirstChild("Gui") then
		local gui = script.Gui:clone()
		gui.Parent = Player.PlayerGui
	else
		if not Player.PlayerGui:FindFirstChild("nope") then
		local guin = script.nope:clone()
		guin.Parent = Player.PlayerGui
	end
	end
	end
	end

script.Parent.ClickDetector.MouseClick:connect(loadscreen)

The part of the script after the 'else' part is the part that does not work. There are no errors in the output. Please help?
