Your use of the phrase "pass/fail values", coupled with the fact you want to
report the word "fail" in another column, suggests to me there are numerical
values in Column A and that there is a certain value marking the point at
which an item is considered failed. However, you didn't tell us what value
marks a failure nor whether numbers higher or lower than it constitute a
failed item. Also, your use of the term "column b1" is confusing as b1 is a
cell, not a column. Given your omissions, I will make some assumptions and
then give you a formula for those assumption (you will have to modify it to
fit your actual conditions). Assuming 123 is the value marking where
failures occur and that numbers equal to or higher than this value are
considered as failed, and that you want the word "fail" in Column B next to
each failed value, then give this formula a try (put it in B1 and copy it
down)...
=IF(A1>=123,"Fail","")
