WHERE Vorders.cvcode = ?Vendors.cVenCode
has a paramater, ?Vendors.cVenCode. The "?" indicates that Vendors.cVenCode is a parameter for the view that should be set before the requery is called. I'm not used to setting up views using a field name from a table as a parameter, I usually go the route of using a variable that would be set, for instance lcVenCode.BROW Order_List
