I've got a table (order), each record got by autonumber his own orderID. Then I got a form with all the records of this table. All this records got a factID this ID is "0" till i've send the bill of that order. What I want is when I got the form on screen, select one order then the module give the record his own factID(=max(factID)+1) and then give the preview of that bill. And also the select all the records with factID="0" and by buttonclick give them all there own factID(which is each time Max+1) and show the preview of that bills. I'm looking weeks for this and I really want to know if it's possible. Thanks in advance.
