/COUNTA(F10,F13,F16,F19,F22,F26,F30)

Try replacing the COUNTA function with the COUNT function:

=SUM(...)/COUNT(...)

I am trying to average a column of percentages but need to exclude some
cells
because they are N/A. The problem is that the cell may be empty but it
has a
function associated with it so it is not being excluded from the average.
I
have tried
=SUM(F10,F13,F16,F19,F22,F26,F30)/COUNTA(F10,F13,F16,F19,F22,F26,F30)but
this
only works if I delete the function from the cell that is N/A. For
example,
I may need F13 to be excluded this time because the numerator and
denominator
were 0 but next time I might need it so I don't want to delete the
function
from the cell. Is there a way to do this? Is it possible to hide the
function so that the cell appears to be empty if there is no number or
letters in it but the function is still being used?
Thanks much
