how to make a single line of function where you can close and open a shop gui?

I can't seem to get how to make the script work

here's the script:

1. local see = true
2. local frame = script.Parent.Parent.Frame.Visible
4. script.Parent.MouseButton1Click:Connect(function()
5. while see do
6. script.Parent.Parent.Frame.Visible = true
7. print ("success")
8. see = false
9. if see == false then
10. frame.Visble = false
11. see = true
12. end
13. end 14 end)

can anyone explain to me how to make the script work so I can press a button to close or open a shop Gui?
