title: use subform filter and orderby parameters for a query
body: <p>I need to create a query to return the same records shown in a subform inside a opened form.
  So I have based the query on the same recordsource of the subform; then, i have set the query <code>filter</code> and orderby properties with <code>[forms]![myformname]![subformcontrolname].[form].[filter]</code> and <code>[forms]![myformname]![subformcontrolname].[form].[orderby]</code>.
  However, the query always returns all the records in recordsource as if filter and orderby were empty. Why?</p>
