Carmel,

To add to Sergey's reply.

A cbo in a grid, is much better behaved if it's RowSource is Array instead of a table/cursor.

>I am using VFP6 and I have a problem with a combobox that I am using within a grid. The combobox rowsource uses Table A. The combobox is bound to the controlsource of Table B. Where the codes are numerically sequential the combobox displays correctly within the grid. However, the combobox appears blank where the codes that link the 2 tables are not numerically sequential. Am I missing a setting ?
