public function actionPrice()
    {
        $divform = new DivisionForm();
        if ($divform->load(Yii::$app->request->post()) && $divform->proc) {

            $k = 1;
            if ($divform->minus != 1) {
                $k = $k * ($divform->proc/100);
            } else {
                $k = $k * ($divform->proc/100);
                $k = 0 - $k;
