How to update a field from a different table?
Say I have a "Many" table called INVOICES and it has a date in it. I'd like to be able to update the parent table, say CUSTOMER, with a single date field whenever one of the invoice dates is either added (new record) or changed.
Is that possible? I can't (as usual) get the syntax to work. Even though the fields display in the dialog trying to to a simple assignment ":=" doesn't work.
