In the Text formula it returns a value of 0

Hmmm...

Try this one:

=SUMPRODUCT(--('C:\Users\[monitor.xls]Adjusting
Output'!$A$3:$A$10001=DATE(2010,3,1)),--('C:\Users\[monitor.xls]Adjusting
Output'!$A$3:$A$10001<=DATE(2010,3,31)))

Thanks for your response but the formula isn't working for me. In the
Text
formula it returns a value of 0 which is incorrect as there are definitely
Mar2010 dates.

In the other solution I get a #value error.

Thanks guys

=SUMPRODUCT(--(TEXT('C:\Users\[monitor.xls]Adjusting
Output'!$A$3:$A$10001,"mmmyyyy")="Mar2010"))

Hi, I have a column that is predominately filled with dates i.e.
1/12/2010;
16/4/2010 etc, and my formula below counted the number of rows based
upon
the
month and year of these dates, this worked well until now. Some fields
within
the column now have text instead of a date and this has now messed up
my
formula which returns a #value error. Any assistance you can give
would
be
greately appreciated.

Thanking you in advance.

=SUMPRODUCT(N(MONTH('C:\Users\[monitor.xls]Adjusting
Output'!$A$3:$A$10001)=3),N(YEAR('C:\Users\[monitor.xls]Adjusting
Output'!$A$3:$A$10001)=2010))
