Script will not repeat when called?

I'm making a shop where if you touch a part it enables the GUI and the X button disables. It works fine but if I try it a second time it doesn't work. Here's the code:

Part enabler (server script):

local part = script.Parent

part.Touched:Connect(function(parthit)
	print("fired")
	local gui = game.Players[tostring(parthit.Parent.Name)].PlayerGui:WaitForChild("TrailShopGUI")
	gui.Enabled = true
end)

X button (local script):

local button = script.Parent

button.MouseButton1Click:Connect(function()
	local gui = script.Parent.Parent.Parent
	gui.Enabled = false
end)

Any help is appreciated!
