I needed a report based on a query and wanted users to be able to edit the query without being in design view. I then made a form with 2 text boxes (becuase there are 2 fields that are typically modified) and built an expression in the query criteria field acordingly. This works fine when both boxes are filled in, but when I only want to use one of the 2 criteria boxes I get nothing but error on my report. Any ideas?
