Dropdown list with:

Rowsource = 'SqlExec(lnSql,[SELECT VehicleType, TypeId FROM dbo.VehicleTypes],[crsrVehicleTypes])'
RowsourceType = 3
Controlsource = 'MakeType.VehicleType'
BoundColumn = 2
BoundTo = .T.

Everything populates ok and looks fine, but when I use the dropdown to select a different vehicletype (i.e. try to change the type) everything stays the same.

What am I doing wrong here?

TIA
