assuming your data is in a1:a8 and you want to exclude 0 values, try

=SUM(IF(ISNUMBER(A1:A8),A1:A8))/COUNTIF(A1:A8,"0")

Hi, I would like to work out the average from a column of numbers but where
no data is available, it reads #N/A or #REF! So I can not use the automatic
system found in auto sum, is there any way around this. Also I think any
average would be influenced by any zeros in the column, Can any one help.
Thanks in advance, Tommy.
