Quiz part2 arrays

Can you please have a look to my code. It does not listed an ordered list with numbers, just with bullet points. I think something is wrong. Please can you explain me. Thank you. https://w.trhou.se/p3w47jiqzv. Quiz number 1 file.

Line numbers are added to ordered lists ("ol"), but there are not any on the page. On lne 33, there is code that adds an "<ol>' tag, but on the next line an ordinary assignment (=) cancels that assignment by putting new contents in place of it.

To add on instead of replace you need this symbol instead :point_right: +=

Also be aware that it's not proper HTML to have anything other than "li" as a direct child element of of a list (either "ul" or "ol").

Examples:

<!-- Good HTML, the list has only "li" inside (child elements) -->
  <h2>...</h2>
  <ol>
    <li>...</li>
    <li>...</li>
    <li>...</li>
  </ol>

<!-- BAD HTML, the list has other child elements than "li" -->
  <ol>
    <h2>...</h2>  <!-- does not belong inside a list! -->
    <li>...</li>
    <li>...</li>
    <li>...</li>
  </ol>

Thank you very much Steven. Can you please explain me again what you want to say with the last sentence. I am still have a lot of thing to learn so it will be helpful to explain in a simpler way. Like, what is a child element? You suggest to not use "li" just "ol"? Thank you a lot for patience .
