Using Excel 2000, I developed a grid incorporating +, -, words and values.
The abbreviated grid looks like this:
B C
3 Average 1
4 + 2
5 + 3
6 - 4
7 + 5
8 + 6
9 + 7
10 Average 8
11 - 9
12 - 10
13 - 11
14 + 12
15 - 13
16 - 14
17 Average 15

In cell B19, I set up the following formula: =SUMIF(B3:B17,"+",C3:C17).
Instead of returning the expected result of 35, the value was 12 (value in
B14). I even tried replacing all of the +'s and -'s (using letters) but the
formual result was 0 instead of 35. What went wrong? Thanks for any help!
