This document provides instructions for concatenating two attribute fields in ArcGIS using VBA logic script. It describes opening ArcMap, adding a shapefile and its attribute table. It explains how to add a new field, open the field calculator, check the advanced box to open the pre-logic VBA script window where you can declare a variable and assign an existing field to concatenate with other text or numbers, like concatenating "MP" with an ID field. The result will be the concatenated values appearing in the new field in the attribute table.
