    $this->load->model('pament_notice_model');

    $postvars = isset($_POST)? $_POST : array("no post");

    print_r($postvars);
    echo "</pre>Refurl:<br><pre>";
    Check for the transaction ID and put it in the pament_notice table if possible.

    if (isset($postvars['item_number']) &&  $postvars['item_number'] > 0 && isset($postvars['txn_id'])){

        log_message('info',"PayPal transaction received.");

        if ($this->pament_notice_model->make_sure_payment_number_is_empty($postvars['item_number'])){   
            //writes the message to the local log file in CI
