Hi this is Pete. If you're using ArcGIS 10, you don't need my old VBA script anymore :). You can calculate the area of polygon features directly in ArcMap. Just create an "Acres" field in your feature class, right-click that field in the Attribute table window, and select "Calculate Geometry". You should be able to choose "acres" as your unit of measure, and off you go!Thanks for responding, Pete!
