I am trying to figure out how to sum certain values in column B, if column A matches a certain criteria.
i.e. Column A has dates in sequential order for all of 2003. Column B has sales per day.
I want to add the sales from column B for all of the Mondays.
Any help would be greatly appreciated.
Thanks.
