No not exactly, I guess I didn't explain the problem well enough. As an example I'll use the Invoice/Customer model (this is actually for a music publishing company but that would just make this more complicated). Say I have a database with 468 Invoices. I want to do a report that summarizes/sorts the invoices by Customer and tells me the number of unique customers in that report either as a grand total or by numbering 1,2,3,4,5,6,... each individual customer. Any summary count fields that I use give me the count of Invoices instead of the count of Customers. Thanks for your input
