Create a method called 'containsBlanks'

Need a second set of eyes, I don't see whats wrong here:

function isValidEmail(email){
    return email.indexOf('@') != -1;
}

function requiredValues(){
  var values = [];
  $('.required').each(function(){
    values.push($(this).val());
  });
  return values;
}

function containsBlanks(){
    var results = requiredValues();
  var blanks = new Array();
  results.each(function(){
    blanks.push($(this) == "");
  });
    return blanks.sort().pop();
}

It looks like you are attempting to call in the requiredValues function from the previous challenge when you do not need it for part 3. To complete this challenge you need to do the following:

(1). declare a variable for your array (2). use the class 'required' with the each() function to include all input fields (3). push() all empty strings into your array (4). sort() and pop() the array so all the true & false values are grouped together

function containsBlanks() {
  var emptyFields = new Array();
  $('.required').each(function() {
    emptyFields.push($(this).val() == "");
  });
  return emptyFields.sort().pop();
}

Let's just say you can answer part 3 with 1 line of code by using the function you coded up in part 2.
