How to enter serial ID from related table? Lookup and calculation don't work
I've got the table "Trading Mistakes" (T1) that is related to the table "List of Mistakes" (T2).
In T1 I have Drop-down list with values from T2. I get correct data from the field "Mistake" of T2 but can not get entered data from ID_List of mistake from T2 into 's always empty and so I can't get T2's related records from T1.I've tried to lookup and calculate auto-enter, no way.
I think I missed something... Any help?
Thank you, Sergey
