sum only if all are numbers, return 'NA' if non-numbers exist. How?
Table:
1 2 3 N 4 N N 2 4 5 1 2 3 4 5 I want to sum each row and expected results are NA, NA, 15 for 1st, 2nd and 3rd row, respectively. I used IF(ISNUMBER(A1:E1),SUM(A1:E1),"NA") and then shift+ctrl+enter. but seems the results are not correct. It always give me 6,11,15..:( any mistake here? thanks. yy |

Hi Bob,
thanks but your fomula will have the same results as mine: 10 11 15. I want to get "NA" for the first two rows.
