Try (in 2007)
=AVERAGEIFS(D1:D10,A1:A10,"=" & DATE(2009,10,1),A1:A10,
"<" & DATE(2009,11,1),B1:B10,"Reported",C1:C10,"*John*")

array formula which will work for 2003/2007

=AVERAGE(IF(TEXT(A1:A10,"mmyyyy")="102009",IF(B1:B 10="Reported",
IF(ISNUMBER(SEARCH("John",C1:C10)),IF(ISNUMBER(D1: D10),D1:D10)))))

Example:
A B C D
1 01/10/2009 Cancelled John, Steven 4
2 01/09/2009 Reported John, Steven 2
3 20/10/2009 Reported John, Darren N/A
4 12/10/2009 Reported John, Darren, Steven 2
5 14/10/2009 Reported Darren, Steven 4
6 15/10/2009 Reported John, Darren 2
How can I average the numbers in column D, but only the ones in rows where A = October, B = reported and C contains "John"? (contains John, doesn't have to be exactly John). Note that there are some text strings in column D, so it is not all numbers - the answer for the example would be 4+2 divided by 2 = 3

Thanks
