#div/0 errors and blank cells

Guest

Hi wondering if anyone can help me with this one...

Have 31 cells in a row which i want to get the average value from, some of
these 31 cellsmay or may not have data in them. The end coloum would be the
one working out the average value of that row of cells.

If no data is entered into any of the cells is it possible to get the
average formular not to return a #div/0 error but instead just return a 0
figure?
Obviously as soon as any data is entered the formular would work as normal
but just want it not to return the error should no data be entered.

The average figures obtained would then be used in a graph.

sure must be a plain and simple answer to this..

=if(count(a1:a5)=0,"",average(a1:a5)).
This will first check if there are any numbers in the range. If not, leave
the result blank; if so, average those numbers.

If your data is in cells A1 through AE1, 31 cells, then you could use:
=IF(ISERROR(AVERAGE(A1:AE1)),0,AVERAGE(A1:AE1))
The ISERROR function will catch any kind of error, not just division by zero
, #DIV/0.
