I have a field "B" that is based on a lookup field "A". It all works perfect when I enter a new record. I select the value form the dropdown in filed "A" and automatically populates field "B". When I import a number of new entries from a civ file, all the values for the field "A" are there but the lookup field "B" is empty. How do I configure the form / field so that field "B" also updates when I import records.
