Counter with No Records Upload Images   Link

User Derek Wright on my YouTube channel brought up a great question:

Thank for this it has really helped me with an equipment inspection database,  one question though is if I start with zero records it does not work but if I already have say a single dummy record in with the number 1 it then works fine. Is there a way around this anomaly?

The solution:

In the BeforeInsert event, wrap the DMax function inside Nz:

OrderNumber = Nz(DMax("OrderNumber", "OrderT"),0) + 1

That will now set OrderNumber equal to ZERO if there aren't any records.
