Try

=SUM(M9,-N9,O9)

or

=IF(M9=0,"",your_formula

Thanks again for your time.
I tried the =IF(M9=0,"",MAX(0,37.5-M9) formula and excel tells me that
ti's
wrong and I should add a ) at the end of the formula. i added it and it
works
great now thanks. However, the colum next to it has this formula and it is
now reading #VALUE! the formula in that cell is: =SUM(M9-N9+O9) how can I
change it.

Ok, that should be easy to fix, the reason is that the sum formula
returns 0

=IF(M9=0,"",MAX(0,37.5-M9)

that would work if the values in I13:L13 never are negative

otherwise use

=IF(COUNTBLANK(I13:L13)=4,"",MAX(0,37.5-M9))

Thanks again, The M9 cell Contains this formula: =SUM(I13:L13) and
there
are
nothing in the I9:L9 rage of cells and when I try your formula it
returns
37.5. Ineed the cell to be blank if if the answer to the formula is
37.5

Where are the numbers entered, the only thing that changes in this
formula
when copied down is the cell reference and if M8 is blank then my
formula
returns a blank, thus copied down it will change to M9, M910 and so on
like
=IF(M9="","",MAX(0,37.5-M9) so it should work

How exactly does the formula look that you copy down, of course if it
is
not
blank it will return the MAX part, blank means empty and not space or
something

Thanks, but it didn't work . Again, when we copy the cell down the
sheet
if
the
others cells are blank, then the 37.5 apears until numbers are
entered.
Can
the formula be "hidden" so cell is blank?

We are doing a time card and have this formula: =MAX(0,37.5-M8)
when
we
insert the formula in the cell and theres no hours for that pay
period
it
shows 37.5 how can we hide the formula so the cell is blank.
