I have an invoice book of 100 invoices. I need something that will
show me the next number to use for the invoice number. The invoice
number series (say 10001 - 10100) is set manually on the covering
worksheet, but i need something to add the correct number to the
invoice, being the next number in the series. Of course I can create
a range of numbers to use, but how will one formula in the invoice
number cell be used to allow for the next number?
