触发电子邮件后未填充Google Apps脚本“ Email_Sent”

Question

很抱歉，有很多代码，但是我快要死了。我正在尝试创建触发器以将电子邮件发送到特定地址，然后将列I标记为“ Email_Sent”。然后，该脚本应在每次提交新表单并检查数据时触发，并检查I列中的“ Email_Sent”，如果存在，则不要触发另一封电子邮件。到目前为止，当我手动运行它时，它仍然有效，但仅适用于第一行数据。谁能帮助我找出导致卡住的原因？这是我到目前为止所拥有的-

 var EMAIL_SENT = 'EMAIL_SENT';

 function sendFormByEmail(e) {
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form Responses 1");
  var startRow = 2; // First row of data to process
  var numRows = 9; // Number of rows to process
  var dataRange = sheet.getRange(startRow, 9);
  // Fetch values for each row in the Range.
  var data = dataRange.getValues();
  for (var i = 0; i < data.length; ++i) {
    var row = data[i];
    var emailAddress = 'alias@email.com';
    var message = "Hey! You have new feedback to review. Check out the tracker to review and acknowledge-"; // Second column
    var emailSent = 9; // In this column, script will write “E-mail Sent.” Future e-mail will not be sent if “E-mail sent” exists
    var emailSent2 = row[emailSent];
    if (emailSent2 != EMAIL_SENT) { // Prevents sending duplicates
      var subject = 'New Feedback!';
      MailApp.sendEmail(emailAddress, subject, message);
      sheet.getRange(startRow + i, emailSent).setValue(EMAIL_SENT);
      SpreadsheetApp.flush();
    }
  }
}
