Google Sheet Script - 未成功的电子邮件自动化

Question

我正在尝试整理一个脚本，该脚本循环显示电子表格中的二维范围;当满足标准时（在这种情况下，在需要续订之前，培训分别是一个月和一周），应发送一封电子邮件。

当脚本只需循环一行包含多行时，我就能实现这一点;但是现在我正在尝试循环遍历多个列和多行，脚本正在运行而没有错误，但数据不会触发要发送的电子邮件。

我正在尝试使用的较小版本的脚本显示在下面，尽管原始版本更广泛，试图覆盖大范围的数据。此处不存在的脚本是需要考虑的每个列的“列”部分的重复。

function trainingReminder() {
//For testing purposes
//You can view the log by typing CMD+ENTER (CTRL + E) after you run the script.
Logger.log(msg);

// grab the Google Sheet object
var googleSheets = SpreadsheetApp.getActiveSpreadsheet();
// activates the first sheet
SpreadsheetApp.setActiveSheet(googleSheets.getSheets()[0]);
// grabs the sheet
var currentSheet = googleSheets.getActiveSheet();

// find the last row
var lastRow = currentSheet.getLastRow();

// The first row starts at row 2 to account for headers
var startRow = 2;

warning_count++;
}
}

if(warning_count) {
MailApp.sendEmail("example@email.com",
"Training Reminder", msg);
}
};

我意识到任何有能力编写脚本的人都可能会有一些非常明显的东西，但不幸的是我还没有它。任何帮助将不胜感激！
