### Summary of data using array formula

• Follow

```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))))))}
```
 0

```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 here:
