Hi there,

I use the following SumProduct formula to search for all values in a
specified date range, in this case, for all values in january, then sum those
values which fall into that date range:

=SUMPRODUCT(--('Daily Reading Master
Log'!B3:B400=DATEVALUE("01/01")),--('Daily Reading Master
Log'!B3:B400<=DATEVALUE("30/01")),'Daily Reading Master Log'!CB3:CB400)

Question: I need to be able to adapt this formula for averaging a set of
values for a specified month range.

can anyone help me on this?
