# Trying to calculate next sequential number using multiple columns

Starting in Cell AI8, calculate the next sequential number using th
last number from Column B. But only calculate for Cell AI8 if AG8
"1'.

In the screenshot attached, Cells AI8 and AI9 should remain blank. AI1
should be 1261. AI11 should be 1262. AI12 should remain blank becaus
AG12 is blank. The next sequential number should be 1263 in AI18

Can't see your screenshot - resolution too low...

Are you looking for a VBA solution or a worksheet formula?

You should take a look at the =MAX() worksheet function, something like:

=IF ( AG8 <> 1 ; "" ; MAX ( AI\$8 : AI8 ) + 1 )

....that's the worksheet formula, I would make, and then copy down as long as
needed.

It should be fairly easy to convert this to VBA, if you want to
