I have a form (header) with a subform (lines) linked to each other by four
fields.
My problem is when I need to change one field in the form (header)
automatically the record in the subform disapears.
I need a way to change the fields linked both in the form and subform at
same time in order to update the records and not lose the line record
because
a linked field changed in the header.
Thank you.
