>I have a form with a big grid whose .RecordSource is the one table in the DE. If I set grid.ColumnCount = -1, the form works fine, with the grid showing me all fields in MyTable. If I make a column and set the .controlsource = MyTable.Myfield, it gives me Error Loading File - controlsource - record number 4 - Alias 'Mytable' is not found. My controlsource was selected using the little combo in that field in the properties form, so I didn't have the opportunity to mis-type the controlsource. What's going on?

Bret, check in your DataEnvironment to see if AutoOpen is .T. Next try to re-create the grid using the standard VFP builder.
