Thanks to you both, made all the difference in the world, adding a second
"date' column in my criteria. I get tunnel vision sometimes and need someone to strike a match so I see my way out. Great service you performn here!

I would agree that a pivot table might be a better fit in that instance. I am trying to understand the "D" functions, however. I have succeeded in getting a successful response with single criterion and even with "AND" criteria. That is when the AND is two separate fields. What I am still having trouble entering is a "RANGE" of criteria, such as all entries between, say 10/1/06 and 10/31/06. Of course in Access I simply enter = 10/1/06 and <=10/31/06 in a criteria, but I have not found how to do this in the Excel criterion cells. Any suggestions? Again I am trying to understand these D functions and their use. Thanks "Debra Dalgleish" wrote: Another option is to use a pivot table to summarize the data. You could view the results by name or group the dates to show a specific year or month. There are pivot table instructions and links he http://www.contextures.com/xlPivot01.html JR Hester wrote: I am attempting to use Dsum and Daverage with a date range. Below is sample of the data I have defined ranges named CRITERION as A1:c3, Variances as A6:C13. My formula is =Daverage(Variances, 3, Criterion). This works for individuals in name column, but not for the date values I have entered here. Trying to get all March entries, #1. can you show me the error of my way? #2 Is it possible to use actual cell references instead of named ranges to define the criterion data?
