Please help me to solve this question.

I have no idea how to solve this problem. "https://teamtreehouse.com/library/jquery-basics/creating-a-mobile-drop-down-menu/getting-a-value"

Please help me.

Here is my code. What's wrong with it?

//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. $titleInput=$previewTitle.text(titleValue).value(); }

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. 
  $titleInput=$previewTitle.text(titleValue).val();

You're close! Rather than putting ".val()" at the end of the last line, you need to set "titleValue" to "$titleInput.val()":

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

I hope this helps!

Thank you very much!
