jQuery .val - unable to retrieve value

Unable to do this- Take a look at the app.js and preview. The aim of this application is to show what the user types in to the input field and preview it in the H1 tag. Almost all the code is there, there's just one thing missing. Retrieving the value from the input. I forgot how to do it. Could you finish it for me? Thanks!

js/app.js 
//Select the input for the title for blog post.
var $titleInput = $("#title");

//Select the preview h1 tag
var $previewTitle = $("#titlePreview");

// Every second update the preview
var previewTimer = setInterval(updatePreview, 1000);

function updatePreview(){  
  //Get the user's input
  var titleValue;
  //Set the user input as the preview title. 
  $("#titlePreview").val($titleInput);
  $previewTitle.text(titleValue);
}
index.html 
<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="theme.css">
</head>
<body>
  <div id="form">
    <label for="title">Blog Post Title</label><input id="title" name="title" value="" placeholder="Enter your blog title here">
  </div>
  <div id="preview">
    <h1 id="titlePreview"></h1>
  </div>
  <script src="//code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
  <script src="js/app.js" type="text/javascript" charset="utf-8"></script>
</body>
</html>
theme.css 
  #form {
    width: 45%;
    float: left;
  }
  #preview {
    width: 45%;
    float: right;
  }
  label {
    width: 20%;
    display: inline-block;
  }
  input {
    width: 70%;
  }

Hi,

the solution to the challenge is,

function updatePreview(){  
  //Get the user's input
  var titleValue = $titleInput.val();
  //Set the user input as the preview title. 
  $previewTitle.text(titleValue);
}

Reference: (http://api.jquery.com/val/)

Thanks, Aishu
