Summarizing All Opportunities, each with an attached Shape, to count Post/Zip Code
A shape can be associated with an Opportunity. That Shape may cover several post/zip codes. We'd like to be able to report on 100 Opportunities and show how many shapes have the same Postcode in common. Why? We want to show how many Opportunities are interested in buying land in the same Postcode. This request is similar to the Geopoint Idea - "Save a data set or shape "membership" to a Record" whereby a record falling within a shape is being counted.
