This could be a very simple question. In the attached twbx, I am trying to create a "yes" field for every client that has an entry for "Submitted by". For example, if a client has a name featured in the "Submitted by" column, the calculated field should make it say "Yes". If "Submitted by" has "null" as the entry, it should say "N" . If the same name is featured twice (in this case Dave is featured twice), both rows should have "Yes" as the answer. Hope someone can help.
