User Registration - Custom Fields

[loky62]

Hi, I use joomla 3 and Virtuemart 3.

I have two problems during the registration process:

1. I added a custom field "CONFIRMATION EMAIL"  and I would like to check that you have correctly inserted the EMAIL standard field (in practice writing emails twice and verifing if they are equal)

2. I added two custom fields "INVOICE YES/NO" and "TAX CODE" and I would like to accept the mandatory "TAX CODE" field only if the user has requested INVOICE YES  (in practice to condition the acceptance of a field)

Are there any tips? Maybe a plugins to solve the problems?

Thank you.

Conditional shopperfields are nasty. Yes you must solve that with a plugin. But when you try to solve the B2B problem in Europe, I suggest to use my plugin
