I think it is a syntax issue. Below is a pretty straight foward function that may help.

    '* This routine is used to write the information to the browser
    Private Sub WriteToBrowser(ByVal sFPath$, ByVal sFName$)

        ' Push File
        Response.ClearContent()
        Response.ClearHeaders()
        Response.AppendHeader("Content-Disposition", "inline;filename = " & sFName)
        Response.ContentType = "txt/txt"
        Response.WriteFile(sFPath)
        Response.Flush()
        Response.Close()

        ' Clean Up (Uncomment below if you wish to remove the file from the server after sending)
        ' System.IO.File.Delete(sFPath)

    End Sub

Thanks,
