Thank you, I was able to use _mstw_tr_last_name and _mstw_tr_first_name to populate these fields.
What I am doing is using Gravity Forms to have players register without having to login to the back end. I have a field called full name that when submitted creates a new post as a player. The issue is the rosters will not display because the actual first name and last name fields are not filled out (just the title of the post with their name).
Is it possible to point me in the right direction to change the code to allow this? Thank you
