Thank you. And this was my first time that the "F" and "B" were emphasized in the column as being apart. I wished I submitted screen shots for those occupations that are like stacked. They have F B then another set of initials right underneath in same box. Then the next line is blank for the name, and there is another set of initials, sometimes double stacked. I can't remember what I assumed. I believe I assumed same name, and added the initials to the set above, following the don't duplicate the names rule.
In future I will be more of a stop and don't assume, screen shot, and wait for reply.
