Sorry for the late reply, but hopefully I can be of some help and get you on your way!

In order to solve this code challenge you need to retrieve the value from the input field ($titleInput) and store the value within the titleValue variable. The value then gets passed into the $previewTitle.text(titleValue) method call.

So, in order to retrieve the value from our input with jQuery we can utilize the val() method on our $titleInput variable. So we would change the updatePreview() function like so: 

function updatePreview(){  
  //Get the user's input -- This is where we can use the val() method to get the input's value
  var titleValue = $titleInput.val();
  //Set the user input as the preview title. 
  $previewTitle.text(titleValue);
}

I hope this was able to solve your issue, and if you have any additional questions don't hesitate to ask!
