How do i resolve an error for auto assign number and email trigger?

问题

I have a script that triggers auto number and auto email to "on form submit". But i noticed that if the email address provided by the sender has a special character or the email path is incorrect, the auto number and auto email stops (even if there are valid email address involved).

How to resolve the error?

Error Message received: ReferenceError: Note is not defined at addAutoNumber(Code:62:2)

function addAutoNumber() {
    var sheet = SpreadsheetApp.getActive().getSheetByName("Responses"); 
    var LastRow = sheet.getLastRow(); 
    var AutoNumberStart=1; 
    if (sheet.getRange(3, 1).getValue() == "Timestamp") { 
        sheet.insertColumnBefore(1); 
        sheet.getRange(3, 1).setValue("Auto Number"); 
        sheet.getRange("A3:A").setNumberFormat(0); 
        if (LastRow>1) { 
            for(var ii=2; ii <= LastRow; ii++) { 
                sheet.getRange(ii, 1).setValue(AutoNumberStart); AutoNumberStart++; 
            } 
        } 
    }

    //AUTO NUMBER 
    if (sheet.getRange(LastRow, 1).isBlank()) { 
        if (LastRow == 2) { 
            sheet.getRange(LastRow, 1).setValue(AutoNumberStart); 
        } else { 
            var LastAutoNumber = sheet.getRange(LastRow-1, 1).getValue(); 
            // Set the next AutoNumber sheet.getRange(LastRow, 1).setValue(LastAutoNumber+1); 
        } 

        // ---- Send a response receipt with the AutoNumber as a reference number 
        var EmailAddress = sheet.getRange(LastRow, 30).getValue(); 
        var recipientsCC = "email@gmail.com" + "," + (sheet.getRange(LastRow, 31).getValue());

        // email subject 
        var Subject = "Subject " + sheet.getRange(LastRow, 3).getValue(); 
        //message body 
        var Message = 'Dear Sir/Madam, \n\nThis is Your Reference Number is: <<< ' + (LastAutoNumber+1) + ' >>> ';
        // Send the mail 
        MailApp.sendEmail({ to: EmailAddress, cc: recipientsCC, from: sender, subject: Subject, body: Message });
    }
}

If your error is related to an incorrect email path, you should validate the email and/or sanitize it if necessary

• Sanitizing can be done with testing() against a Regex expression representing a correct email address e.g.

/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/

• Validating can be performed e.g. with String replace() against a regex expression that allows only valid characters like replace(/[^\w\s]/gi, '')

Sample:

    var EmailAddress = sheet.getRange(LastRow, 30).getValue(); 
//validate email
    if(EmailAddress !=" " && EmailAddress != " "){     
      var EmailAddress = "gre@gerg.de";
      var emailFormat = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
      if(!emailFormat.test( EmailAddress)){
//sanitize email
        EmailAddress = EmailAddress.replace(/[^\w\s]/gi, '');
      }
      var recipientsCC = "email@gmail.com" + "," + (sheet.getRange(LastRow, 31).getValue());      
      var Subject = "Subject " + sheet.getRange(LastRow, 3).getValue(); 
      var Message = 'Dear Sir/Madam, \n\nThis is Your Reference Number is: <<< ' + (LastAutoNumber+1) + ' >>> ';
      MailApp.sendEmail({ to: EmailAddress, cc: recipientsCC, from: sender, subject: Subject, body: Message });
    }
