Hi again :),

You've made exactly the same mistake as you did in your other question. Once you have declared a variable, in your case var section = document.querySelector('section');. You don't need to declare the right side of it again when you try to get the children of the section. You can use variable name instead of declaring everything again. Instead writing everything out again on your second line -

//your code
var section = document.querySelector('section');
var paragraphs = document.querySelectorAll("section").children;

//try this
var section = document.querySelector('section');
var paragraphs = section.children; 

I really recommend you reading more about declaring and using variables :). Here's a link again - Read more about variables
