I designed and built a database and all queries, macros and reports have worked as designed for months. I am the only user. Out of the blue I have a parameter query that is no longer producing any results. I made no changes to any report, form, or query. The parameter query gets its field values from text boxes on a form. Up until today the query ran as designed. Starting today the query no longer produces any results. I’ve attached some screen shotes of the error messages and circumstances. See the attachment for screen shots and detail information. Any help is appreciated. (I can't post the database)
