I seem to not understand correctly what is required from me

Below is the code I am using that does not work. Any ideas what I should be doing?

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 = prompt('Please enter a value');
  //Set the user input as the preview title. 
  $previewTitle.text(titleValue);
  $previewTitle.val(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%;
  }

Hey, Dan ...

You're trying to have the user enter the title value from a pop-up window, but that's not what they asked you to do. They want you to pull the title value out of the input form element.

If you look at the HTML, you can see the input has the id of "title", so you can use that to select it. And then you can use jQuery's val() method to retrieve it's value.

Here's what it should look like:

var titleValue = $("#title").val();

Note: I verified the code passed the challenge.
