Greetings all,

I have 3 columns of info in a MI table as follows
 
          Capacity 1   Capacity 2   Capacity 3

Site 1  10                30               10
Site 2   0                  10                0
Site 3   10                0                  20

and I want to work out for every row the average of the 3 capacities but ignoring the 
0's in any of the columns.

Therefore results would be in a new column

               Avg Capacity

Site 1  16.7
Site 2   10
Site 3   15

HAs anyone come accross a solution for this problem.

Thanks

Tony
