Good afternoon. I have one small concern with my dbase. I decided to use sequential numbering instead of the Access autonumber. I also put in pessismistic locking to keep people from screwing up records being edited. I have seen alot of date and sequential number procedures, but I am going with just a straight 1 2 3 type sequence. When the form opens the number already appears in the text box. How much do I have to worry about a duplicate number appearing? And if it is a problem, is there an easy way to correct it? I have about 20 users. Thank you to anyone answering this one.
