All, using ms access 2010. I have a report based on a query. I have two fields that are set up in the table as yes/no fields. When I filter this field; the drop down is yes no but upon selection it's -1 or 0. When I click to view the report; it tells me either too few parameters or the message I set up " there's no criteria for this report". All other filter fields are fine. Is there something else I have to do to be able to filter yes/no fields? Thanks
