You have two things going on

(1) There is no reference to widget.js in your index.html file. The following is included in the head of the video's workspace html 

<script src="js/widget.js"></script>

Without it none of the javascript executes.

(2) The initialization in your for loop in widget.js has a syntax error. Instead of:

for(var = i; i<employees.length; i+=1){

it should be

for(var i = 0; i<employees.length; i+=1){

Hi Vera Gominho ,

Pretty close with your code so don't worry.

Issue

There were two updates I needed to make to get your code working.

  1. The widget.js wasn't included in your index.html via a script tag.
  2. An error in the widget.js employees for loop.

Fix

Including Script in Index.html

Near the bottom of your index.html file ensure you include a script link to your JavaScript file.

  </div>
  <script src="js/widget.js"></script>
</body>
</html>

For Loop

Your for loop was for(var = i; i<employees.length; i+=1). It should look like this:

for(var i = 0; i<employees.length; i+=1){

It was probably just a typo but when using for loops you need to assign a number as a starting index.
