エラー”NullReferenceException: Object reference not set to an instance of an object”

view〇（数字）のオブジェクトに〇（数字）の名前のマテリアルをスクリプトで反映させたいです。
以下のスクリプトを実行して最初は反映されていたのですが、途中からエラーが出るようになりました。
きっと何かをいじってしまったのだと思いますが、、

＜エラー内容＞
NullReferenceException: Object reference not set to an instance of an object
Automation.Start () (at Assets/Automation.cs:30)

30行目は
”m_Renderer1 = view1.GetComponent<Renderer>();”
のところです。その下も同じような記述が続いているのに、これだけ反応したのも疑問です。
よろしくお願いします。
