I'm working on calculating the monthy average for a % of time worked by
person by project. I'm able to create the right formula, but when I extend it
to other rows the color is background is changed as well. Because I inserted
a row for the monthly average, I have the correct color in the row and I
don't want to change it or that the value is a % in the cell.

=IF(ISERROR(AVERAGE(P3:S3)),"",(AVERAGE(P3:S3)))

My next step will be to create another worksheet that will contain the
monthy average from sheet 1.

Using Excel 2003
