Need help on the Technical documentation page, please

Not sure why test 12 doesn’t work. Here is my codepen:

Hey @cnorf Welcome to forum. Text in nav bar should be same as the text in the section heading but here:

            <a class="nav-link" href="#JavaScript_&_Java">
              JavaScript and Java

Heading of this corresponding section has “JavaScript & Java” but your li element has “JavaScript ans Java” both of these should be same.
