Product landing page 15/16 I am stuck (solved)

Hello everyone, i’m sorry to make a post out of what is probably a simple fix but I am totally puzzled.

No matter what I do the test won’t read my nav links.
What did I do wrong?

It appears that your nav element is not finished.

 <nav id="nav-bar"><ul>
         <li><a class="nav-link" href="#header">Why?</a></li>
         <li><a class="nav-link" href="#bottom">Pricing</a></li>
         <li><a class="nav-link" href="#email">Email list</a></li>
        <li><a class="nav-link"  <!--Something is missing here -->
        <ul>
        </nav> 

I just facepalmed myself. Thank you.
That code was leftover from a previous edit.
