表格脚本，提示电子邮件地址发送表格为pdf

Question

我正在尝试提供一个菜单项，提示输入电子邮件地址，将Google工作表作为pdf报告发送电子邮件。我几乎在那里，但我在最后一行收到错误。
＆＃34; GmailApp.sendEmail（电子邮件，主题，正文，{附件：[文件]}）;。＆＃34;

错误内容如下 ＆＃34; ReferenceError：＆＃34; email＆＃34;没有定义。 （第76行，文件＆＃34;代码＆＃34;）＆＃34;

我在这一行上缺少什么来完成脚本以通过提示成功发送电子邮件输入？

  var sheet = SpreadsheetApp.getActive().getSheetByName('Testing');
  var range = sheet.getRange("A4:P40");
 var formulas = range.getFormulas();
