試したこと

何をすればいいかわかりません

補足情報（FW/ツールのバージョンなど）

htmlに0列:時刻,1列:行先が書かれています。時刻の切り替わりの前以外は正常に動作します。プレビュー:リンク内容

Answer 1

インデントが乱れているためコーディングのミスに気付くのが難しくなっています。
問題のある個所のインデントを整えてみました。

              if ( nhour == time[0] ) {
                if ( nmin <= time[1] ) {
                  break;
                } else if ( shour == time[0] ) {
                  break;
                }
              }

ミスがわかりますか？
修正するとこうです。

              if ( nhour == time[0] ) {
                if ( nmin <= time[1] ) {
                  break;
                }
              } else if ( shour == time[0] ) {
                break;
              }

4か所ありますので、4か所とも修正してください。
