I see what you are trying to do here, but it doesn't work for my application
(the 9AM and 10AM was just an example). Is there any way to use AND/OR with
COUNTIF? Thanks.

How do I use the COUNTIF and the AND functions together? I tried using
the
following formula and got an error:

=COUNTIF(and((B4:B27,"=9 am"),(B4:B27,"<=10 am")))

It works fine for me using time values. did you format the cell as number
or general instead of time. are your values really just time values.

This is the general solution and works in all cases (times, dates, numbers,
text - any place a single countif would produce an accurate count if there
is only one criteria) when properly written.

Countif/sumif don't work with AND/OR. Maybe you would feel more comfortable
with the slower sumproduct approach offered by Sebastion.

I figured out how to make it work using your solution. At first the formula
was returning the wrong values but I made a few changes and it works well
now. Thanks a lot for the help. You saved me a lot of time trying to do it
the "wrong" way.

what if you have 3 columns to check?

with an array like

1 1 3
2 1 2
2 1 4
1 2 3
1 1 3

How do you count the number of "1 1 3" occurances?

Try a formula like

=SUMPRODUCT(--(A1:A5=1),--(B1:B5=1),--(C1:C5=3))
