Google apps script 抄送不工作邮件合并（谷歌脚本在谷歌工作表），我是初学者

所以，基本上我是在为老师写一些代码，以便在抄送学生家长的同时，能够将他们的成绩邮寄给学生。我真的不知道发生了什么，但只有一个家长

这是代码，大部分是复制粘贴的基本google代码，我添加了第25-26行来说明家长电子邮件，我在第94行取消了cc代码的注释，并添加了我认为正确的代码（我不太编码，我甚至不知道这是什么语言）

我要怎么做才能解决这个问题

问题: 您希望在抄送列表中有多封电子邮件，但当前代码将只读取并放入行[RECIPIENT2\u COL]的值

解决方案： 请尝试将代码的第94行改写为：

cc: row[RECIPIENT2_COL] + "," + row[RECIPIENT3_COL],
