Overloaded constructor error when creating trigger programmatically - google-apps-script

Question

I want to create a process, when person submits a form and I get only filled in information (not every field is required for filling). Found code (http://www.labnol.org/internet/google-docs-email-form/20884/), did everything according to author, but doesn't work me. I'm not a specialist in coding, so I need your help.
Here is the code:
function Initialize() {
var triggers = ScriptApp.getScriptTriggers();
for(var i in triggers) {
ScriptApp.deleteTrigger(triggers[i]);
}
ScriptApp.newTrigger("SendGoogleForm")
.forSpreadsheet(SpreadsheetApp.getActiveSpreadsheet())
.onFormSubmit()
.create();
}
function SendGoogleForm(e)
{
try
{
// You may replace this with another email address
var email = "justbeincredible#gmail.com";
// Optional but change the following variable
// to have a custom subject for Google Form email notifications
var subject = "New Driver Application Arrived";
var s = SpreadsheetApp.getActiveSheet();
var columns = s.getRange(1,1,1,s.getLastColumn()).getValues()[0];
var message = "";
// Only include form fields that are not blank
for ( var keys in columns ) {
var key = columns[keys];
if ( e.namedValues[key] && (e.namedValues[key] != "") ) {
message += key + ' :: '+ e.namedValues[key] + "\n\n";
}
}
// This is the MailApp service of Google Apps Script
// that sends the email. You can also use GmailApp for HTML Mail.
MailApp.sendEmail(email, subject, message);
} catch (e) {
Logger.log(e.toString());
}
}
Here is what I get when I run Initialize to test:
Cannot call overloaded constructor forSpreadsheet with parameters
(null) because there is more than one matching constructor signature:
interface SpreadsheetTriggerBuilder forSpreadsheet(Spreadsheet)
interface SpreadsheetTriggerBuilder forSpreadsheet(String) (line 12,
file "Code")

Answer 1

Add the code inside the Script Editor of the Google Spreadsheet that is collecting the responses and not inside the Form editor.
[source]
Explanation: The error message indicates that forSpreadsheet() had a parameter of (null). You fed it SpreadsheetApp.getActiveSpreadsheet(), so that evaluated to null. That method is only applicable within Spreadsheet-bound scripts.

Answer 2

The add-on doesn't work on brave browser. Try running on Google Chrome if you are not currently using it.
