调用app函数时出现脚本错误

Question

function sendalert(e){

    var sheet = SpreadsheetApp.getActiveSheet();
    var emailAddress = "avisekh12310@gmail.com";
    var subject = "Price Alert - " + e ;
    var message = "Hi Price alert triggerred," + e;

    MailApp.sendEmail(emailAddress, subject, message);

MailApp.sendEmail(emailAddress, subject, message);
