I stand corrected. I've never seen the double unary (two minus signs)
before.
Always learning around here!

Hi Denise

The formula looks fine, as long as your floor identifiers in column I are
text 3 and not numeric 3. They need to be all of the same type, and as the
formula shows the figure "3", I assume they are all supposed to be text.
Are they? Do they have any leading or trailing spaces?

Otherwise, have some of your times been entered in the wrong format?

It should work out for you if your data is correct.

I am using the following formula:

=SUMPRODUCT(--(I4:I400="3"),--(S4:S400<=TIME(0,45,0)))

The spreadsheet that I have has different floor numbers (3-7) that are
in
column I. I need to count how many had times of < = 45 minutes on each
floor. This is the formula that I got from someone here.

My numbers are not matching. So far for this month for admissions to
the
3rd floor that are <= 00:45 I have 7, the formula is showing 4.

Can anyone help me!!! The only reason that I noticed this is that we
have
had 33 admissions to the 3rd floor. All of the times that this formula
is
giving me do not add up to 33.

TIA.
