I want to use the Multi Select function in the list box for a filter in a query, But as soon as I select Simple or Extended my query comes back blank. If I leave it at None, I can select a value as use it in my filter to run a query. I know I have data in the table I am trying to query against. Does anyone have any Ideas? It seems so simple, I was thinking I was missing a setting or something. I am using Access 2007. Thanks for any advice
