>>You will find that you keep your sanity much longer if you realize that the grid doesn't have any records in it, it is a display function only. It is the RecordSource for the grid that has records in it. Keep this straight in your mind and you will avoid a whole lot of headaches and late nights.

>Ok, good point. Related question: If I have SET FILTER on a table, what is the easiest/best way to detemine how many records are in the filtered result?

With SET FILTER (which Inhate BTW) you have only COUNT command (that's part of why I hate SET FILTER I much prefer using a SELECT to get data filtered into a cursor then _tally is available to you)
