Mike:
You made a good catch, although it didn't solve this problem. It solved a problem that I was going to encounter right after I fixed this one. You are right that I didn't set the Order in the Policy table (a Grandchild table). However, right now, I am trying to fix the relationship between Case (Parent) and mmPolCse (Child). I did set the Order of mmPolCse right after I selected it, and before I set the Relation. Also, the Relation is working fine, but only after I Browse Case and select a record.
