Portals: Add new records
On the layout of Table T1 I've got 2 portals, from Tables T2 & T3, to which I can add records. Tables appear to relate correctly: T1 < T2 < T3 in that if I pull up a record for T1, the appropriate records from T2 and T3 appear in portals.
Problem: When I create new records in T3, it always relates to the first record in T2 for any particular record in T1. I'd like to be able to add T3 records to say record 2 from T2, then add T3 records to say record 3 from T2 etc. I'm sure this is v. basic, but how do I specify which parent records, the new child records relate.
