I've made a close button for my Shop GUI but it isn't working, how to fix?

I've made a close button script and when I click the button on the shop gui nothing happens.

            script.Parent.MouseButton1Click:Connect(function()	                                                                                                    
                                                                                                        
         script.Parent.Parent.Visible = false
                                                                                                                                           
   end)

Is there something wrong with my script?

try removing one of the parents from

 script.Parent.Parent.Visible = false 

and placing this

local btn = script.Parent

btn.MouseButton1Click:Connect(function()
	print('clicked') --change this accordingly

into a script inside of the button
