Dealing with a non-existant table...

Friends,

I have a piece of code that, when activated by a timer, selects a set of results from a particular database.  It works great if there are records or not, but if the table doesn't exist, it breaks.  What syntax is required to deal with a returned message of "Invalid object name 'Results'."?  Ultimately, I want to return 0's for my values, but...

Syntax help requested please!

Here is my code:

Public Sub GetCurrentSessionResults(ByVal dsnCurrentRun As String)

        Try

            Dim data As New DataSet
            Dim r As DataRow

            Dim con As New SqlClient.SqlConnection(dsnCurrentRun)

            'fill in the data for a lap ...
            data = New DataSet

            Dim dr As SqlClient.SqlDataReader

            con = New SqlClient.SqlConnection(dsnCurrentRun)

            con.Open()

            Dim c As New SqlClient.SqlCommand("Select Laps = Sum(Laps) from Results", con)

            dr = c.ExecuteReader(CommandBehavior.SingleResult)

            Dim found As Boolean
            Dim cmb As ComboBox

            Dim i As Integer
            found = False
       
            If dr.HasRows Then
                While dr.Read()
                    If dr.IsDBNull(i) Then
                        CurrentSessionLaps = 0
                        lblCurrentSession.Text = CurrentSessionLaps
                    Else
                        CurrentSessionLaps = dr.Item("Laps")
                        lblCurrentSession.Text = CurrentSessionLaps
                    End If
                End While

            End If

                con.Close()
                con = Nothing

        Catch ex As Exception

            MessageBox.Show(ex.Message)

        End Try

    End Sub

Thanks in advance!
