Good afternoon --

I have a sumproduct formula with four conditions. One of them needs to test
a range of cells for either a "N" or a blank. I can write it to test for one
or the other, but not either one. Here's my formula:

=SUMPRODUCT(--($A$2:$A$2000=$H28),--($F$2:$F$2000=I$3),$E$2:$E$2000,--($D$2:$D$2000=""))

It's the 'D' column -- I need it to test for either a blank cell or an 'N'.

Any help would be appreciated.

TIA
