大幅に改訂されたプロジェクトの後(すべての入力に感謝します)、私はまだautorateLottery();をループできません。私のコンソールは私に言い続けます -

TypeError: document.getElementById(...) is null document.getElementById("random_0" + i).value = rnd;

私は自分のプロジェクトをhttp://jsfiddle.net/Ulleruller/2q2ne/17/に掲載しました

これが何を意味するのか、誰か教えてくれませんか？

私がそれを終わらせることができるよりも -

それはまさにそれがあなたに言っていることを意味します. ID「random_0」+ i を持つ要素はありません。この場合、「random_01」から「random_06」までになります。
