Working with a personal geodatabase, I am trying to calculated a field for a layer that contains 5000+ polygons based on the sum of 7 other fields. I.e., every polygon has either a "1" or a "<null>" value in each of the 7 fields. If one of the polygons has 4 "1" values and 3 "<null>" values, I want my new field to show a "4."
When I carry out the calculate field command (sum_all= [field1]+[field2]...etc.) the program takes several hours to process the command, but no change occurs in the new (sum_all) field.
I hope that there is a simply solution, any help is much appreciated!
