Technical Documentation Page - Help in error

I don’t know what error my code is getting, I’ve reviewed everything several times and I haven’t seen anything wrong, but it’s not passing the test.
Can someone help me?

My code:

I’d check the spelling on the id for “Function declarations”.

Also, when the nav menu is on the left side it doesn’t scroll if the height of the browser is shorter than the menu so you can’t click on the menu items that fall below the bottom of the view port.

Thank you! I hadn’t seen it. I already solved both problems.
