Summary of data using array formula
I have a spreadsheet where there are several columns with data using
validation picklists as well as free-entry columns. I would like to create a summary of the data in the form of counts based on the existence of specific values in these columns with the ability to change the date range. I've created the array formula and have set up a 'startdate' and 'enddate' cells where the user can enter the range they're looking for. No matter what I do the value always reports a zero. I have used these types of array formulas before, however, not using date ranges. Could there be something I'm missing? DOI = Date of Incident {=COUNT(IF(ROU_Stat="CE",IF(IncType="Near Miss",IF(DOI=$C$1,IF(DOI=$D$1,IF(Region_Stat="qc ",1,0))))))} |

Summary of data using array formula
I'd try:
=sumproduct(--(rou_stat="CE"), --(inctype="near miss"), --(doi=$c$1), --(dou=$d$1), --(region_stat="qc")) This assumes that all the ranges contain single columns (or rows) and each have the same number of elements. And that DOI, DOU and C1, D1 are all real dates--not just text that look like dates. Adjust the ranges to match--but you can't use whole columns (except in xl2007). =sumproduct() likes to work with numbers. The -- stuff changes trues and falses to 1's and 0's. Bob Phillips explains =sumproduct() in much more detail he http://www.xldynamic.com/source/xld.SUMPRODUCT.html And J.E. McGimpsey has some notes at: http://mcgimpsey.com/excel/formulae/doubleneg.html Smitee2006 wrote: I have a spreadsheet where there are several columns with data using validation picklists as well as free-entry columns.
