I am developing an application with customers and contracts. A customer may have 0, 1 or more contracts. I'm trying to create a table with number of customers with different number of contracts. Like
No of Contr.
No of Cust.

Is there a way of doing this without counting the number of contracts per customer in the script? I wouldn't like to do that because I'd like the count to change with selections.
