Thank you. 
Please be as precise as possible, because your request is slightly confusing.
By “after”, do you mean “below”?
Your registration form contains a “Profile Headline” field, but I suspect it has nothing to do really with what you ask. You are asking, to my understanding, to put a user’s title below their username
I tried my code from my message on your forum and it works:
Before:
After:
Is that what you want?
