Email not sent on Google Form submission - google-apps-script

Question

My aim is every time a user submits a form. The form goes to a spreadsheet but also the contents get summarised and sent to two emails. Always the same emails.
function myFunction() {
function submitForm(e){
// FormApp.getActiveForm()
var itemResponses = e.response.getItemResponses();
var message = '';
for (var i = 0; i < itemResponses.length; i++) {
var itemResponse = itemResponses[i];
var question = itemResponse.getItem().getTitle();
var answer = itemResponse.getResponse();
message += (i + 1).toString() + '. ' + question + ': ' + answer + '\n';
if(answer === 'English'){var send=1;}
if(answer === 'Japanese'){var send=2;}
if(answer === '身上異動届（結婚届）'){var send=3;}
if(answer === '住所・通勤経路'){var send=4;}
}
var address1 = 'test1#gmail.com'; //★Your Email Address
var address2 = 'test2#gmail.com'; //★Your Email Address
var address3 = 'test3#gmail.com'; //★Your Email Address
var title1 = '【氏名変更】Someone has submitted a form.';
var title2 = '【銀行口座変更】Someone has submitted a form.';
var title3 = '【身上異動届（結婚届）】Someone has submitted a form.';
var title4 = '【住所・通勤経路】Someone has submitted a form.';
var content = 'The form was submitted with the following contents.\n\n' + message;
var option = {};
option.from = "info#gmail.com";
if(send === 1){var to1 = [address1, address2, address3];
GmailApp.sendEmail(to1, title1, content,option);}
if(send === 2){var to2 = [address1, address2, address3];
GmailApp.sendEmail(to2, title2, content,option);}
if(send === 3){var to3 = [address1, address2, address3];
GmailApp.sendEmail(to3, title3, content,option);}
if(send === 4){var to4 = [address1, address2, address3];
GmailApp.sendEmail(to4, title4, content,option);}
}
}
}
But it seems that no email get sent.
I don't quite understand what's wrong
Link to form
Link to spreadsheet

Answer 1

You are not creating the script at the right place.
Please newly create a script and then create the trigger from the script editor of the form.
Reference:
Creating a bound script
You could found your trigger is different from jcb01's
function submitForm(e){
// FormApp.getActiveForm()
var itemResponses = e.response.getItemResponses();
var message = '';
for (var i = 0; i < itemResponses.length; i++) {
var itemResponse = itemResponses[i];
var question = itemResponse.getItem().getTitle();
var answer = itemResponse.getResponse();
message += (i + 1).toString() + '. ' + question + ': ' + answer + '\n';
if(answer === 'English'){var send=1;}
if(answer === 'Japanese'){var send=2;}
if(answer === '身上異動届（結婚届）'){var send=3;}
if(answer === '住所・通勤経路'){var send=4;}
}
var address1 = 'test1#gmail.com'; //★Your Email Address
var address2 = 'test2#gmail.com'; //★Your Email Address
var address3 = 'test3#gmail.com'; //★Your Email Address
var title1 = '【氏名変更】Someone has submitted a form.';
var title2 = '【銀行口座変更】Someone has submitted a form.';
var title3 = '【身上異動届（結婚届）】Someone has submitted a form.';
var title4 = '【住所・通勤経路】Someone has submitted a form.';
var content = 'The form was submitted with the following contents.\n\n' + message;
var option = {};
option.from = "info#gmail.com";
console.log(send, content);
if(send === 1){var to1 = [address1, address2, address3];
GmailApp.sendEmail(to1, title1, content,option);}
if(send === 2){var to2 = [address1, address2, address3];
GmailApp.sendEmail(to2, title2, content,option);}
if(send === 3){var to3 = [address1, address2, address3];
GmailApp.sendEmail(to3, title3, content,option);}
if(send === 4){var to4 = [address1, address2, address3];
GmailApp.sendEmail(to4, title4, content,option);}
}

from triggers menu set a trigger to run "your script" immediately on form submission

function submitForm(e) {
var itemResponses = e.response.getItemResponses();
var message = '';
let send = '';
const option = {from:"info#gmail.com"};
for (var i = 0; i < itemResponses.length; i++) {
var itemResponse = itemResponses[i];
var question = itemResponse.getItem().getTitle();
var answer = itemResponse.getResponse();
message += (i + 1).toString() + '. ' + question + ': ' + answer + '\n';
if (answer == 'English') { send = 1; }
