Hi Geoff.

As Nadya already mentioned, effectively using a combo in a grid can be tricky, especially if you leave the grid column's sparse property set at its default (true). If your combo is bound to some foreign key value but displays the descriptive text from a lookup table, the descriptive text will be displayed only when the grid cell with the combo has focus. All the other rows will display the foreign key.

You can set the grid column's sparse property to false or for an alternate solution you can look at my article "Spice Up Your Grid With A Combo" from FoxPro Advisor, February 2000.
