页面导航不适用于最终的for循环迭代

Question

我已经使用Apps脚本创建了Google表单。表单利用嵌套的for-loop来将用户定向到表单的正确部分。但是，对于最内层的循环（用户单击以提交其响应），该循环的最终迭代不提供“提交”的选项-它表示“继续至下一部分”。

为您提供一些背景信息。这是一个父母晚上约会系统，用户首先选择一位老师，然后再选择他们希望在那里约会的日期。 for循环的最后一天是星期四，星期四是“继续进行下一步”的日子，应说“提交”。

该表格在星期四循环之前每隔一天有效，我不确定为什么。

星期三

星期四

我已经指出了需要用星号（*）纠正的代码部分

function updateForms() {
  var setUpSheet = ss.getSheetByName('Set-Up')
  var times = setUpSheet.getRange(2, 2, setUpSheet.getLastRow()-1,1).getValues()
  var teacherNames = setUpSheet.getRange(2, 1, setUpSheet.getLastRow()-1, 1).getValues()
  Logger.log(teacherNames)

  var appointmentRange = setUpSheet.getRange("C2:C").getValues()
  var appointmentRangeCount = appointmentRange.filter(String).length
  var appointmentDays = setUpSheet.getRange(2, 3, appointmentRangeCount, 1).getValues()
  Logger.log(appointmentDays)

// Opening page where user selects the teacher

  var page1 = form.addPageBreakItem()
  page1.setTitle('Parent\'s Evening Appointment System')
  var item = form.addListItem()
  item.setRequired(true)
  var teacherPages = []

  for (var n in teacherNames) {
    var appointmentPages = []
    var teacherName = teacherNames[n]
    Logger.log(teacherName)
    var newPage = form.addPageBreakItem().setTitle(teacherName)
    teacherPages.push(item.createChoice(teacherName, newPage))
    var item2 = form.addListItem()
    item2.setTitle('Choose Day')
    item2.setRequired(true)
    for (var i in appointmentDays) {
      var appointmentDay = appointmentDays[i]
      Logger.log(appointmentDay)
      var newPage2 = form.addPageBreakItem().setTitle(teacherName + ' ' + appointmentDay)
      appointmentPages.push(item2.createChoice(appointmentDay, newPage2))
      var item3 = form.addListItem()
      item3.setTitle(n + '. Please choose your appointment time. ' + i)
      item3.setRequired(true)
      item3.setChoiceValues(times)
      newPage2.setGoToPage(FormApp.PageNavigationType.SUBMIT)*********
    }
    item2.setChoices(appointmentPages)  
  }
  item.setTitle('Select your child\'s teacher.')
  item.setChoices(teacherPages)
  SpreadsheetApp.getActiveSpreadsheet().toast('Task Complete', 'Status');

}

我该如何解决？
