I've worked all day on this with no luck. I need the detail page to have a session variable of the record ID just like "$_SESSION['WADA_Insert_tblVendors']". Unfortunately "$_SESSION['WADA_Insert_tblVendors']", which appears in the bindings Session and can be dragged onto the page, but will not work to filter a record set.
I need to create several additional recordsets based on it. ADT I could set a custom trigger to collect the record ID and pass it to a session variable.
