title: Getting undefined/no result when printing out api callback
body: <p>I am trying to run my script that is going to search for a movie title from a movie database. I get results in the console and no errors. But in my <code>renderMovies</code> function it's supposed to store the API movie title, plot etc in my variables, but when I print it out in a list it either gives me nothing (blank) or <code>undefined</code>. I am kind of new to jQuery, AJAX and APIs so I'm following a guide, so the code is not entirely written by me. </p>
  
  <p>OBS: I get undefined when using this <code>$("&lt;td&gt;" + plot + "&lt;/td&gt;")</code>, but blank when using <code>$("&lt;td&gt;").append(title)</code>. You can find that code in the middle of the renderMovies function.</p>
  
  <p>For example: I search for the movie 'Avatar' and I get two results. However the two results gets "stored" as <code>undefined</code> in the plot description and blank from the title.</p>
  
  <pre><code>$(document).ready(function(){
    $(init);
  
    function init() {
      $("#searchMovie").click(searchMovie);   
      var movieTitle = $("#movieTitle");
      var table = $("#results");
      var tbody = $("#results tbody");
  
      function searchMovie(){
        var title = movieTitle.val();
  
        $.ajax({
          url: "http://www.myapifilms.com/imdb/idIMDB?title=" + title + "&amp;token=b81c6057-20cf-4849-abc4-decbf9b65286&amp;format=json&amp;language=en-us&amp;aka=0&amp;business=0&amp;seasons=0&amp;seasonYear=0&amp;technical=0&amp;filter=2&amp;exactFilter=0&amp;limit=1&amp;forceYear=0&amp;trailers=0&amp;movieTrivia=0&amp;awards=0&amp;moviePhotos=0&amp;movieVideos=0&amp;actors=0&amp;biography=0&amp;uniqueName=0&amp;filmography=0&amp;bornAndDead=0&amp;starSign=0&amp;actorActress=0&amp;actorTrivia=0&amp;similarMovies=0&amp;adultSearch=0&amp;goofs=0&amp;keyword=0&amp;quotes=0&amp;fullSize=0&amp;companyCredits=0&amp;filmingLocations=0",
