Hi @jemo ,

It is difficult trying to find the issue without the code.
Could you please share the link to your code.

Hello,

You have 2 typos on your nav-links:

<a class="nav-link" href="#Program_Design_&_Logic">Progrm Design & Logic</a>

Missing and a on Progrm

and:

<a class="nav-link" href="#C_&_Arrays">C & Array</a>

missing an s in the Array

Thank you very much for the asssistence.

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

Pre-formatted-text

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
