Kevin,

This should do it:

thisForm.grid1.column4.controlSource = 'childTableName.stoneID'
thisForm.grid1.column4.rowSourceType = 3 && SQL
thisForm.grid1.column4.rowSource = 'select stoneID, description from stonesTable order by stoneID into cursor aTemporaryCursor'

Where 'stonesTable' is the table that you want to populate the combo box, and 'childTableName' is the recordSource for the grid.

>How do I add a combo box to the grid, which is bound to one
>table while being populated from another?

Good luck,
