.. It still does not count blanks in column C

This part in the expression should have taken care of it:

..+(C2:C10="")..

Perhaps there are white space(s) in the cells,
these cells might appear "blank" but are not really so.

Try wrapping a TRIM around the range, viz try:
=SUMPRODUCT((A2:A10="Fred")*(B2:B10<"bob")*((C2:C 10="AA")+(TRIM(C2:C10)="")))

you are a champion. I used the following and it works a treat
=SUMPRODUCT(('Grid data'!B9:B4563=A9)*(ISERROR(SEARCH("bob*",'Grid
data'!D9:D4563))*(('Grid data'!F9:F4563="aa")+(TRIM('Grid data'!
F9:F4563)=""))))

Thanks very much Max
