Using an "IF" formula, I need to leave empty the empty cells (I mean,
cells containing nothing). I tried many ways, f.e., putting a "" if
the
formula finds and empty cell, but Excel (2003) puts something all the
times.
Thanks to all.

Look at this formula:
=IF($A14=0,"",$A14*G14)

See the two commas in the middle, surrounding the double quotation
marks?
Do you have something like that in your formula?

Thank you, but my problem is a little more complex: I have a column with
all
the cells containing only "1" or "0" or being empty. I need to reverse
the
"1"'s into "0"'s, and vice versa, and to leave the empty cells as they
are.
I'm not able to find how to do it.
