Is there a bug for lesson 11 of 18 API?


I am concerned as I believe that I may be doing something wrong or that there may be a computer error occuring.

Any help as soon as possible would be beneficial so that I can start actually working on projects.

API lesson, click here

function expandUrl() {
  const urlToExpand = url + 
        '?key=' + apiKey +
        '&shortUrl=' + $inputField.val();
  url: 'urlToExpand', ///the instructions are asking me to put urlToExpand here


Do I put a comma after urltoExpand? I believe I am making a syntax error possibly and may be missing a concept that I do not understand.
