        {
            replyArticles.ReplyCategory = db.Articles.Where(m => m.ArticleIDX == replyArticles.ReplyArticleIDX).Select(m => m.Category).ToString();
            replyArticles.ReplyDepth = 1;
            replyArticles.ReplyIndent = 2;
            replyArticles.ReplyDate = DateTime.Now;
            replyArticles.ReplyMemberID = User.Identity.Name;

            db.ReplyArticles.Add(replyArticles);
            db.SaveChanges();

            ViewBag.Result = "OK";
        }
        catch (Exception ex)
        {
            ViewBag.Result = "FAIL";
