Your code pretty much looks correct. The only thing that I see is that you don't initialize Thisform.pnCombo until after the combo has been instantiated. Since Thisform.pnCombo is a logical when the combo initializes, that may be a problem. Try moving the code that initializes Thisform.pnCombo to the form's Load method.

>On my form there is a combo with 4 items, the PK is different from the listindex so I used BoundTo=3, every time I select another value the display of the combo blanks. If I remove the controlsource it works ok but then I can't use the combo to put in a initial value. If I set BoundTo to .f. it works ok but then I get the listindex in the controlsource and not the PK. Below I attached some of the code I used.
