Answer 1

Here's something that's clearly stated crookedly.
It must have been methods.

public void shopPan_SH
    {
        shopPan.SetActive(!shopPan.activeSelf);
    }
 
    public void exchPan_SH
    {
        exchPan.SetActive(!exchPan.activeSelf);
    }

In your case, it seems that the editor should highlight in red the places where the code is written crookedly.
