Do you want to sum quarterly based on a column of dates and amounts? If
so
use


=SUMPRODUCT(--(A1:A365=--"2005-01-01"),--(A1:A365<=--"2005-03-31"),B1:B365)

for the date range from Jan 1 to Mar 31

Hi all,
I have a yearly cost in a column, I need to create another column for
quarterly cost with the source taken from yearly cost column. Am I
right

choose offset funtion in this case and if yes, how to set the correct
one
(especially regarding the "height" in the function criteria).
Any help would be much appreciated.
