It's bug in combobox bound to a numeric property with RowSourceType 2 or 6. To workaround it either unbound combo or use some other RowSourceType, like 5-Array or 3-SELECT.

>I have a combobox on my form with the following properties set:

>.BoundColumn = 2
>.BoundTo = .T.
>.ControlSource = m.pbenefit
>.RowSource = pplans.desc, benefit
>.RowSourceType = 6
>.ColumnCount = 1

>The field benefit is numeric (hence the .BoundTo = .T.) as is m.pbenefit. However, when I select an item from the list, although m.pbenefit is set to the correct value, the DisplayValue of the combobox gets wipes out making it look as though nothing was selected.
