try

=IF(ISBLANK(A2),"",IF(A2<0.3,"",A2-A1))

or in a neater format

=IF(OR(ISBLANK(A2),A2<0.3),"",A2-A1)

Hope this helps

I have the following set-up with 3 cells:

A1 - a target percentage value (30.00%)

A2 - the actual value

A3 - the deviation

Each cell is formatted for percentages. I have inserted the following
formula into A3:

=IF(ISBLANK(A2),"",IF(A2<30,"",A2-A1)

The formula is supposed to do either of three things:

1. If there is no value in A2, leave A3 blank.
2. If the actual percentage is 30% or lower, leave A3 blank.
3. If the actual percentage is over 30%, calculate the deviation from
the standard.

However, The fromula is not behaving! No matter what I do, the A3 cell
remains blank! What have I done wrong???
