I needed to pre-populate the first and last names on a form that is used by registered users.
To do this, I followed instructions from another post to create two single line text fields and use merge tags {user:first_name} and {user:last_name}.
However, the form is bringing in the first word of the display name for the first name and the second word of the display name for the last name.
Why is it using display name data instead of first and last name data?
