you can use the WEEKDAY function so you don't need a range.

=SUMPRODUCT(--(WEEKDAY(A1:A10)=2),B1:B10)

Hello. I am having a problem with extremely long formulas, and I was
wondering if there was any way to tidy them up a little bit.

I have a set of data that has a column with the date it was entered
into the spreadsheet. I am currently trying to gather all the data
that was entered on Mondays.

ie. The dates 38719, 38726, 38733, 38740, 38747, and 38754 (all the
Monday dates in 2006).

I am currently using sumproduct formulas to determine the dollar value
of items entered on Mondays, are a certain type of item, and another
criteria. So my formula currently looks like:

=sumproduct((Criteria 1)*(Criteria 2)*(Criteria 3), (Dollar Value))

This works fine for a range of dates or a single date, but I am curious
if there is any way to be able to put the range of above Monday dates
into a single criteria field of the sumproduct formula. I would also
love to know if there is another way of doing this without using
sumproduct.

Thanks much!

Nick
