How about where col a is your dates and 4 is April and col B is the values
to add.

=sumproduct((month(a2;a22)=4)*b2:b22)

Hi,

I have a spreadsheet which lists Sales and dates that those orders are to
be
delivered on. These dates do not run consecutively on the spreadsheet
though.
I want to produce a formula that will add up the volume of all orders from
a
set date (First day of the month) up to todays date + 1 (Tomorrow) So at
any
time in the month I have a figure that shows the volumes of all orders
delivered up to tomorrow.
