Hello

I'm trying to figure out how to adapt a sumproduct formula so that i can
count the number of rows where, for example,

PwC is in column A
New is in column B
Nutrition is in column C OR Nutrition is in column D

A B C D
PwC New Nutition Writing
Carer Return Writing Nutrition
PwC New Writing Nutrition

The answer should be 2 using the table above. I have been using this
sumproduct fomula to count where three variables occur, but can't see how to
adapt it.
=SUMPRODUCT(--(B4:B87="New"),--(A4:A87="PwC"),--(C4:C87="Nutrition"))

Help would be very much appreciated!
