    Hi,

    I have created two plugins:
    1. To add 3 custom fields on register form
    2. To add this 3 custom fields on checkout page and user dashboard panel.

    I have successfuly added my fields but on checkout page I cannot populate them with the presaved values.

    Fisrt plugin is for adding new fields in registration. The new fields are: ‘billing_bulstat’ ; ‘billing_mol’ and ‘billing_adres’. They are succesfuly saved and displayed in user dashboard panel. The code is:
