I can't find my mistake - Getting a Value - jQuery Basics

I have tried multiple different things, but always the same error comes up: 'Bummer! When I type in to the input "Hello World" I get ".' I don't really understand what is going wrong. Here is my code: Here is my code:

//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. $previewTitle.text(titleValue); var $anchor = $(this); $titleIinput.val($anchor.attr("h1")); }

Can anyone point out my mistake? Thank you in advance.

Your code:

function updatePreview(){
  //Get the user's input
  var titleValue;
  //Set the user input as the preview title.
  $previewTitle.text(titleValue);
  var $anchor = $(this);
  $titleIinput.val($anchor.attr("h1")); // almost, but the $anchor variable is not required
}

The solution:

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