I've copied a report and linked it to a new query. The report has some fields that are not included in the new query, so I've deleted those fields from the report--or I believe I have. However, every time I open the report, it wants a parameter entry for one of the fields. I've searched everything I can think of to figure out where this field or a reference to it still resides in the report but can't find it. How can I determine why the report still wants data for this field?
