invoice numbering a report only??

[Guest]

How can I put invoice numbers that automatically change on a report? I need
to do this because, I invoice customers monthy, for a group of orders created
during the month for thaat one customer, but don't send their invoice until
the end of that month, so the invoice created is a report on the monthy
orders 'booked up' by that customer. I just don't want to number every
single order, just one at the end of the month that will become the tax
invoice number, auto-number preferrably.
thanks

Put in defaultvalue
"E" & Format(Date();"aa") & "/" &
Format(IIf(IsNull(DMax("MioContatore";"MiaTabella";"MioContatore like '?" &
Format(Date();"aa") &
"/????'"));1;Right(DMax("MioContatore";"MiaTabella";"MioContatore like '?" &
Format(Date();"aa") & "/????'");4)+1);"0000")

where "E" is optionalMitabella is your table
Miocontatore is your counter
