Try this (normally entered):

=SUMPRODUCT((YEAR(Z4:Z3500)=2007)*(AN4:AN3500={"Re ferred to Tx","AC
Initiated"}))

I could use an "array formula" suggestion on my problem..........

I've created a database in Excel, and I am trying to use the array formula
below to count for me, but it is only working if I use a single search
criteria in Row AN (e.g. AC Initiated or Referred to Tx) but not both.

What I'd like to do (as the formula is attempting to execute) is count all
client's who were seen during the 2007 calendar year, and identify those
2007
client's who were "referred to tx" and those who began tx (e.g. AC
Initiated). I didn't know if an Array formula can search for multiple
criteria in the same row twice (once for all 2007 clients who were
"Referred
to Tx" and then again for all who initiated tx (AC Initiated). I've tried
several variations of the formula below with no success. Any suggestions?
Thank you in advance, Dan

The Formula I was using that isn't working is:

=SUM((--(YEAR(Z4:Z3500)=2007))*(AN4:AN3500="AC
Initiated")*(AN4:AN3500="Referred to Tx"))
