    Re: no value given for one or more parameters

    Check your select statement. Make sure that all the fields referenced in your where clause actually exist in the table and are spelled exactly the same. Check the values of the variables and make sure they all contain a value.

    Use Debug.Print to save the actual SQL QUERY that gets calculated, and paste that into ACCESS connected to the same tables. Access will point to the character that fails, so it's easy to test, then put back into VB
