how do we automatically fill the other field which correspond to the
record selected in the TIB_lookupcombo

i have try this

procedure TForm_stocks.IB_LookupCombo1CloseUp(Sender: TObject);
begin
parent.fieldbyname('unit').asstring:=lookup.fieldbyname
('unit2').asstring;
end;


but I think this isn't the solution after all.
