Hi!

Are your values in C1:C12 TEXT or formatted dates? They
look like TEXT to me.

Lets assume I have a spreadshee. Cells A1-A365 has dates
from January 1st
2004 to December 31st 2004. Cells b1-b365 has values. And
cells C1-C12 I have
the months as follows Jan04, Feb04, Mar04, Apr04 etc. I
want to compute all
the values for January 04 and put the result in cell d1
(for Jan), D2 for
Feb, D3 for Mar etc.
how can I do this using sumif? My problem really is how
can I compare the
months so Jan04 compares to 01Jan04, 02Jan04, o3jan04 etc?
