Try this:

Dates in the range A1:20
Values to sum in the range B1:20

=SUMPRODUCT(--(YEAR(A1:A20)=2006),B1:B20)

using formula =SUMIF(range, criteria)

for that range and criteria, can we apply using date instead of range?
Such that we the date can be arrange from year 06. So that all information
fall under 06 will auto add up.

any tips?
