I am using Access 2003. I have a field defined as text one position. It will contain only "A" or "H", but this is not included in the properties. If I query the table, I can select either value, and get a valid dataset. In another query, using several files. I try to select by this field. If I try "A". I get a valid dataset. If I try "R" or "T", I get an empty dataset. If I select "H", I get a "Data type mismatch" error. I believe this identifies the error as "Error 3464. I am running out of things to try. Any suggestions? Thank you.
