VBA - AfterUpdate

Hi guys,

I have a Form (frmMainMenu)
Which has a listbox (lstVehicles)
and a SubForm (frmVehicle)

Inside the subform, I have a number of textboxes linked to the Table tblVehicle, but I want to do this...

When the value inside the field "Driver" changes, I want to Insert the new Driver's name into tblDriverHistory, as well as update the current driver name inside tblVehicle.


What's wrong with the code I have so far guys?

Private Sub Driver_AfterUpdate()
    Dim rs As DAO.Recordset
    Dim sDriverName As String
   
    ' Get most recent Driver`s name
    Set rs = CurrentDb.OpenRecordset("SELECT TOP 1 DriverName FROM tblDriverHistory WHERE VehicleUID=" & Me.Parent.lstVehicles.Value & " AND DriverName='" & Me.Value & "' ORDER BY UID DESC")
    Do Until rs.EOF = False
        sDriverName = rs!DriverName
        rs.MoveNext
    Loop
    ' Check Driver Name is not null
    If sDriverName <> "" Then
        ' Check Driver Name does not match New Driver Name
        If sDriverName <> Me.Value Then
            ' Insert new Driver into History Table
            CurrentDb.Execute "INSERT INTO tblDriverHistory (VehicleUID, DriverName, StartDate) VALUES ('" & Me.Parent.lstVehicles.Value & "', '" & sDriverName & "', '" & Date & "')"
            ' Update current Driver in Vehicle Table
            CurrentDb.Execute "UPDATE tblVehicle SET Driver='" & sDriverName & "' WHERE UID='" & Me.Parent.lstVehicles.Value & "'"
        End If
    End If
End Sub


Cheers!
