I have a report that is based on a query. It works fine but I am puzzled as to the existence of a field in the field list selector. it is called Expr 1004 and does not appear in the underlying query and when i select it to be displayed on the report it brings thru the primary key field for a related table - which is in the underlying query but is not in the report (it is a lookup field that would only display the number rather than the actual word)
