 * Hi,
    I was reading the documentation and it really helps on the majority of the
   topic I needed to know about. So thank you. I was wondering if it’s possible 
   to check the validation on multiple fields. In particular I need to know if: 
   in a group field it’s possible to check if at least one of them its populated
   and once it’s checked if the content of the field it’s already in the data system.
 * There’s a way I can do that? If it requires additional payed support or plugin
   I can acquire that too.
 * Thanks.

 * This plugin normally only validates one field at a time. While it is possible
   to create a custom validation that is more complex, checking on the values for
   multiple fields for instance, this requires custom code.
 * I do not provide custom coding services, you will need to find a developer to
   help you with this if you do not have the required skills yourself.
 * I do have a technical article that explains how this is done:
