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))))))}
