I have a field group named cb_dog3, which includes the subfields cb_dogname and cb_rabiesexpire. In an auto action, I'm using the condition [cb:userdata field="_cb_dog3_0_cb_dogname" /] is not empty and  [cb:userdata field="_cb_dog3_0_cb_rabiesexpire" /] is empty, I want to make the rabiesexpire subfield required and return an error message. Have I set the condition up correctly? Is there a PHP code (or other way) that will do this?
Field Group = cb_myfields
First Row = 0
Field = cb_favoritecolor
This would give a substitution of the following.
[cb_myfields_0_cb_favoritecolor]
It's generally not ideal accessing the nested fields though. You'd have to know the exact row number and there's not a guarantee that row would always exist. Ideally you'd use PHP and access them via the JSON. Example as follows using the above.
