Please keep in mind - that the default "Couple" adds an option for another user entry on account creation. I have a similar scenario - Clients and Providers - and just created a new field with those options for a user to select one on account creation.
Yes, I know that the second entry for couples is added. I need that option. The examples I gave are not the actual types I'm using. Actually, all I need to do is change the word 'single' to a different word & change the word 'couple' to different word and not add the second entry.
Then, at the bottom of the general info where it has 'sex' option - male/female, I would like to add couple as a third option there. If they select couple, then add the second entry.
