Hi there,

You're very close! You just need to add an 'a' to show that you want specifically the <a> tags inside of nav. It'll end up looking something like this:

let navigationLinks = document.querySelectorAll("nav a");

var nav = document.getElementsByTagName('nav')[0];//we get the nav element 
var lis = nav.getElementsByTagName('li');// we get the li elements inside nav
console.log(lis.length);// it will display the number of the li Elements inside nav Element.
