In your program, it's ok to have: tmpfile = tmp+sys(2) copy to &tmpfile use (m.tmpfile) alias GridSource and then have: Thisform.Grid.RecordSource = "GridSource" This will allow the grid to always see the same alias, as was suggested. As to the other point: your data is jumbled. This is because the RecordSource file closes and then re-opens. In this process, the all of the customization is lost. Before the RecordSource file changes, you should issue: Thisform.Grid.RecordSource = "" and after it changes you should issue: Thisform.Grid.RecordSource = "GridSource" to restore the data. This will preserve the mappings of the fields, and other customization that you have made to the grid (like the ReadOnly property). HTH
