Moises,
Did you change the data in the form? If so, then you'll need to call either TableUpdate() or TableRevert(). If you have NOT changed the data, then check your combo boxes. When you assign a value to a bound combo box it will update the value of the bound field. You may need to unlink the combos from the fields (save the data in LostFocus() or Valid()).
