Hello everyone! I'm not sure how to word this, but I have a picture! I'm pretty new to Access, so please forgive me. I have a main table that I'm working with and a subordinate table under that and then two subordinate tables to that one. Now, when I go to expand the first subordinate table...it references back to itself. Now, I've checked the relationships and they seem to be fine. I even deleted them all and redid them. Now, I do know that this message popped up when I was doing all of this and it asked me something about tables and relationships, but I don't remember what exactly. Please help. Thanks in advance.
