Good afternoon, I need to add a section to the checkout form, below the 'Shipping/Billing Address' section, to include the private buyer’s tax code (16 alphanumeric characters). The field labelled 'VAT ID NUMBER' in the 'CONTACT' section might also work, but it is currently limited to 11 characters. In Italy, however, 16 alphanumeric characters are required for the buyer's tax. What can be done? Thank you. Andrew
