>>OK - unless this combo is in a grid, the only reason that the combo would come up blank is that the value of the controlSource is not in its internal list - even though it may superficially look like it is. In this case you need to check the respective data types, etc. of the controlSource and RowSource to ensure they match. Verify BoundColumn and BoundTo to make sure that you are binding to what you think you are.

>Well, I got it working doing this: I am assigning ControlSource to a field of the cursor that actually does not exist at the time of loading. VFP does not complain. Later on that curso will be created. So when time comes to show the combo it looks fine. But now I am having another problem. When I click on the combo it looses its dislpay value. Next problem to work on. :(

Can you assign ControlSource (and RowSource) after everything is in place (all cursors exist)?
