I'm running the Multiple Ring Buffer tool on a points feature class. The resulting buffer layer attribute table does not include the field for "Field Name (optional)," which is supposed to be the field in the output feature class that stores the buffer distance used to create each buffer feature. I need that field to feed into future steps in my analysis. I've run the Multiple Ring Buffer tool many times before and not had this problem. Is ArcGIS having an off day, or are others experiencing this problem?
