I just can't seem to figure out which formula to use to make this work.
I've got invoice dates in column D (D4:D233) and Invoice Amounts in column E
(E4:E233).
I need to do two things: count the number of invoices in each month, and sum
the invoices for each month.
I was able to get the count formula correct, as an example
for January:
=SUMPRODUCT((MONTH($D$4:$D$223)=1)*1)
But can not figure out how to SUM column E (invoice amounts) for each given
month.
Your assistance is appreciated.
