Recording mileage on a form

I have a form that has three fields.  "Vehicle Used", "Starting Mileage" and "Ending Mileage".  The "Starting Mileage" field is to show the last entry made in the "Ending Mileage" field UNLESS it is the first record for that vehicle.  In that case the field is to show nothing.

Right now I have this in the control source of the x field but it doesn't work correctly:

=DMax("[EndingMileage]","tblTravel","[VehicleUsedID] = " & Nz([Forms]![frmTravel]![cboVehicleUsedID],0))

are you storing all three of these values in your table, or just the vehicleUsedID and the EndingMileage?

Personally, I would store all three in the table, bind them to the controls on your form, and use the cboVehicleUsedID AfterUpdate event to populate the value of the StartingMileage field (control).
