I need help with a SQL Insert staement with paramaters.

I need help with a SQL Insert staement with paramaters. The insert is called from a button on an ASP.NET page.

This is what I have:
Protected Sub btnNewQuoteHist_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles btnNewQuoteHist.Click
         Dim conStockSelector As SqlConnection

        Dim strConnection As String = "Data Source=BURCEL05;Initial Catalog=StockSelectSQL;" _
        & "Integrated Security=SSPI"
        lblFileDate.Text = Me.calQuoteDate.SelectedDate
        conStockSelector = New SqlConnection(strConnection)
        conStockSelector.Open()
        Dim strInsert As String
        strInsert = "INSERT INTO DownLoadHistory " _
        & " VALUES (@DL_FileName,@DL_Date,MarketID,@DL_Appended);"
        Dim cmdSQL As SqlCommand = New SqlCommand(strInsert, conStockSelector)
        cmdSQL.CommandText = strInsert

        cmdSQL.Parameters.Add("@DL_FileName", Data.SqlDbType.NVarChar).Value = "ABC.txt"
        cmdSQL.Parameters.Add("@DL_Date", Data.SqlDbType.DateTime).Value = calQuoteDate.SelectedDate
        cmdSQL.Parameters.Add("@MarketID", Data.SqlDbType.SmallInt).Value = 2
        cmdSQL.Parameters.Add("@DL_Appended", Data.SqlDbType.Bit).Value = 0
        cmdSQL.ExecuteNonQuery()
        'Error The name "MarketID" is not permitted in this context
        'Column names are not permitted
        conStockSelector.Close()

I just need a hint on one of the Parameters.Add variables.

Thanks,
