Tell us what’s happening:
Describe your issue in detail here.
When you run the test I get, every .main-section nav-link must have an href. I have five sections and everyone of them has an href, so I don’t see why is failing.

  **Your code so far**

Link to the challenge:

syntax issues.
How should hrefs look like if they are referring to something on same page?

Thank you big time. I got it. Finally pass. [quote=“Angel13101415, post:1, topic:531860”]
href="#Advance_Gaming_Computer". This is the right syntax.
