First, ensure you've got the columns you need set on your project list. For example, Contract Total will give you the totals for all signed contracts & the Venue Column to confirm results. You can learn more about adding Custom Columns to your project list here.
Next, click 'More Search Options' on the left.
Then, type in the name of the City you'd like to view in 'Venue'.
Quick note: this will generate results for any matching street, city, county, state.
Finally, to view the Contract Totals for those areas, hover over the Contract Total column to see a sum for all of those projects.
