Calling Stored Procedures Via Vb.net

Hi,

 I was wondering if someone can tell me why my sub for calling stored procedures doesn't work.
The string strFinFileId is not null.

I keep getting the following error System.IndexOutOfRangeException: Total

Here's my sub.

 '//get GrandTotal
    Protected Sub GetGrandTotal(ByVal finfileid As String)
        Dim myConnection As SqlConnection
        Dim connString As String
        Dim strFinFileId As String
        Dim strGrandTotal As Decimal

        strFinFileId = finfileid
        connString = ConfigurationManager.ConnectionStrings("PMOConnectionString1").ConnectionString

        myConnection = New SqlConnection(connString)
        'you need to provide password for sql server
        myConnection.Open()

        Dim sql1 As String

        sql1 = "GetGrandTotal " & Convert.ToInt32(strFinFileId)

        Dim myCommand As SqlCommand

        'Response.Write(sql1)
        'Response.End()

        myCommand = New SqlCommand(sql1, myConnection)

        Dim reader As SqlDataReader = myCommand.ExecuteReader()
        While reader.Read()
            strGrandTotal = reader.Item("Total")
            LabelGrandTotal.Text = strGrandTotal
            'Response.Write(strFinFileId)
            'Response.End()

        End While
        reader.Close()
        myConnection.Close()
    End Sub

 Cheers

Mark :)
