I'm using Excel 2003 so I hope I'm not limited here.

We are performing a space usage survey and I need to compile the data
results. Each location has 70 entries over the course of 10 days. I have a
column for "group work" where the value is either 1 or 0. I have another
column for # of people observed in a particular office. What I'm trying to do
is the following:

Get a count of instances where "# of people" = 1 and "group work" = 0

I'm doing a lot of countif statements, but I don't see how to do a countif
with an and operator. Help??!!
