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 ---------------------------------------------------------------------- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
