Interesting.
There are two databases. Cresta\Customers.nsf is the original database and Crest\CrestaMobile.nsf which is the application I am using to create the mobile application.
The Accordion control in CrestaMobile.nsf is accessing the view in Customers.nsf as it is populating the categories. But it appears not to be able to access it a second time to populate the extra columns.
Ah well I will stare at it for a bit longer and then give up until tomorrow.
