I am working on a spreadsheet that is relatively simple, but I need to have
empty cells and cells input with a 0 to give a referenced cell different
values. I have used the following formulas to do this for a cell with a 0
in it but I have found that this interprets an empty cell the same as a cell
with a 0 in it.



Cell C2 Ex.1: =IF (A2+A3=0), " " , SUM (A2:A3)

RESULTS: If I enter a 0 in A2 or A3 or if I leave A2 or A3 empty the
returned value will be blank.



Cell C2 Ex.2: =IF (A2+A3= " " ), " " , SUM (A2:A3)

RESULTS: I get the same results as Ex.1.

Input Data

Output Data

2

What I need is: IF (A2 AND A3= Blank ) THEN return blank, ELSE SUM (A2:A3)
[even if the value(s) entered into A2 and/or A3 is/are 0 or any combination
of zeros and blanks, I need it to return a 0.]



Thanks for any input.
