O.k. This may not make a whole lot of sense, but I am going to give it a shot.


I need a formula that will add two cells, but return a value of zero, if
either of the two cells themselves equal zero.

Here is the reason.

I have a queationnaire and a follow-up questionnaire with 7 questions and I
am trying to find the average difference for each question answered by each
individual and then find the total average difference , but I need to
exclude any questions that an individual did not answer the question on both
questionnaires because a value of zero on one questionnaires scews the
results.

Is this even possible? Or if anyone knows an easier way to do this it would
be appreciated.

Let's say the 2 values are in cells A1 & A2. Use the array formula

=And(A1:A2<0)*(A1+A2)

Array formulas are entered by pressing Ctrl-Shift-enter, instead of Enter
alone

Try this:

=AND(A10,A20)*A1+A2
