I want to add the values in the RESULT field from two rows which are similar but the numbers are inverted. For example I want to add the values from the row with SUB_REGION field having 1 and SUB_REGI_1 field having 5 to the row with SUB_REIGON field having 5 and SUB_REGI_1 field having 1. These are actually calculations from commuter data between sub-regions. So I want to have the RESULT value to contain the sum of values from people commuting from 1 to 5 and from 5 to 1. Any way I can do this with a script? It seems impossible to me at the moment.
