I need to take something from cell J7 which could be a number or text. If it is a number, I need to determine if the number qualifies as a 'Pass' or 'Fail', and if it is text, I need it to return 'n/a'. Currently, the pass and fail work, but if it is text then it returns False instead of the 'n/a'.

Help please. Here is my current formula:

=IF(ISNUMBER(J7),IF(J7<=187,"FAIL",IF(J7>=188,"PASS","n/a")))

Thanks!
