Google apps script 如何使用Google脚本返回特定单元格的值

我正在尝试返回特定项目的可用数量。Google ss从响应表单中读取，并根据响应表单更新项目的数量—quantityRequested。我遇到的问题是，每件商品的更新量都相同。经过一点修补，我现在得到了“未定义”的结果，我不知道为什么。有人知道如何显示特定项目的新值吗？我还遇到了一个错误：“您没有调用setValue的权限（第167行）”-有什么建议吗

对于（var i=2；i您可以使用以下线程引用：和。使用返回此范围值的矩形网格的方法。例如：
var title=SpreadsheetApp.getActiveSheet（）.getRange（lastRow，2）。getValue（）

Awesome，修复了它！谢谢
