For example, a name could be misspelled or a field may not be available within that scope. To resolve this behavior, rename the reference to a valid field name. If you do not know where the reference is located, run the Database Documenter for the object listed in the Enter Parameter Value dialog box, and then output the information to a text file.

When you want to limit the results of a query based on the values in a field, you use query criteria.
A query criterion is an expression that Access compares to query field values to determine whether to include the record that contains each value. For example, = "Chicago" is an expression that Access can compare to values in a text field in a query. If the value for that field in a given record is "Chicago", Access includes the record in the query results. This topic lists several examples of query criteria.

Convert your Access 2007 application from design to runtime mode by changing its extension. Having your Access application run in runtime mode prevents users from modifying or deleting objects from the application, providing users with access only to the objects you wish. Mary Ann Richardson shows you how to lock down your database and keep it safe. When you're ready to move your Access application from development to production, you need to ensure that it runs in Access runtime mode when opened.
