Thank you for the replyNick_M, but it doesn't work.  I have classes set up, performed the steps you outlined to set up my tour groups a while ago.  When I filter by class (my tour group), the payment transaction drops off the report so the passenger shows he owes more than he does because the payment doesn't have a class associated with it, even though the payment was applied to an invoice with a class associated with it.  It seems we are 2-for-1 now.  Two of Intuit's support believe the documentation, that we can filter transactions by class, and one says we can't.
