 * Hello,
 * I’m using this solution: [https://www.wpdesk.pl/blog/walidacja-nip-flexible-checkout-fields/](https://www.wpdesk.pl/blog/walidacja-nip-flexible-checkout-fields/)
   
   to validate PL NIP number and it works on the checkout, but unfortunately the
   validation doesn’t work on My Account -> Billing Address view..
 * The second issue – is it possible to show/hide the field on My Account -> Billing
   Address only for specific countries?
 * Thanks,
    Pozdrawiam 🙂 Piotr

 * Hello [@kuperman87](https://wordpress.org/support/users/kuperman87/)
 * The plugin supports the Checkout form fields and this validation will work on
   the Checkout page. It will not work on other pages that are not Checkout. Our
   other custom validations work the same.
 * The second issue is related to the conditional logic which is part of the PRO
   version but on this forum we cannot discuss topics related to the PRO version.
   Please write to us if there are additional questions about this feature.
