I'm not really seeing a problem but then maybe I'm missing a point. If a field in a table is a yes/no field (checkbox) and you select it and want to only see selected records, your query would include True or -1 as criteria on that field. Anyone who doesn't want to see just those records (i.e. they want to see all of them) will be able to see them. Sounds like you're playing around in tables though, and that's usually not a good idea. If the check will be True one time then False then True again, this is not the best way to retrieve records.
The more we hear silence, the more we begin to think about our value in this universe.
