When trying to count the number of same values in one column Excel does count
a number of these, but then gives only zero to answer value.

It is like this:

column A column B


11.11.2002 0:01:00 11.11.2002 0:01:00
11.11.2002 0:01:00 11.11.2002 0:02:00
11.11.2002 0:02:00
11.11.2002 0:03:00
etc.

column C

=COUNTIF($A$1:$A$lastvalue;B1)
=COUNTIF($A$1:$A$lastvalue;B2)
etc.

On count 1 answer should be 2 (there is 2 times cell matching cell B1)
On count 2 answer should be 1 (there is 1 times cell matching cell B2) etc.

But Excel (version 2002 SP3) does this randomly and gives answers mostly
zero when copying the function in column C down. What to do ?

Thanks, TT

Try:

C1: =COUNTIF(A:A;B1)

and copy down.

IF that doesn't work, are you sure all your data is entered as
date/times rather than text (or, conversely, text rather than
date/times?)?

Are the values in 'A' date-time stamps? They could be a fraction of a
second off of the value in column B and they would not match. That
would be the first thing I would check. That would explain the
randomness that is happening.
