Thanks Guarav,

Works for all months except January - not all of the cells contain data
yet.
I have a sumproduct formula calculating something else and know that you
add
--(YEAR(RP!$E$5:$E$200)=2009) into the formula.

is something similar required in this, and if so what/where.

=AVERAGE(IF(MONTH($O$5:$O$200)=1,$P$5:$P$200))

This is for January. Change 1 to 2 for Feb, 3 for March etc.

It is an array formula and needs CTRL+SHIFT+ENTER not just ENTER.

Hi

I have a list of numerical values (P5:P200) in O5:O200 is a
corresponding
date as to when the values were recorded. How can I calculate an
average
of
values collected within a specific month.

Thanks
