I am trying to use Display Suite (newest version) to format the profile page for users. I am using the Profile2 module and the default main-profile type. I have the user's full name (not username) split into the fields for first, middle, and last. I am trying to create a custom field to combine these three fields as the full name.
I am trying to create a code field but I don't know what variable or replacement pattern to use. There is nothing in the list of available tokens. I have tried php using $content and $entity and get undefined variable errors.
How can I create a custom field in Display Suite to combine these three fields from a Profile2 entity?
