You need to create the var 'values' at the beginning.

var values = $(".required").map(function() { 
    return $(this).val();
});

You only need to use .required as the selector and the jQuery map method returns a jQuery object, which contains an array, so you can assign the whole jQuery statement to the values variable like this .

Read more about it here

var values = $('.required').map(function(){   
    return $(this).val();
});
