Simplest method is a report layout.
Change the body part to a sub-summary part, in options, sorted by your City field.
Place the city field in the sub summary part layout
Create a new field called Count_city. It should be a field type of summary, and the parameters will be Count of your city field, with the summarize repetitions set to Individually. Place that field in the sub summary part. If you want a total of all cities, also place that part in the footer on the layout.
Then, sort by your city field
If you see nothing, usually its because you didn't sort by the field you picked in your sub-summary part
edit: Also meant to add, on your layout, for this report you only need a sub-summary part, header and footer are optional-no body part
That worked like a charm......
Thank you so much!!!!!!
