I am trying to introduce some people to ArcGIS Maps for Office. When playing around with some test data, I noticed I was unable to aggregate my data by county, I am however able to aggregate the data by zip,state, and etc. Am I missing something there or did that data need to be transformed before hand before one computes it at the county level?
Example Columns:
| Location Name | Location Description | City | State | County | Zip | Total_Collection | Latitude | Longitude | Dates Available |
