It looks like you're on the second task, which builds on the first task. The first task asked you to assign the value of the input to the variable inputValue, and the second task has you take that value and assign it to the textContent of the <p> element with a class of info. You will need 2 lines of code for this.

let inputValue = document.querySelector('input').value;
document.querySelector('p.info').textContent = inputValue;

Remember that when you are referencing a class, it starts with a period ( . ), just like when you do your CSS. This allows you to append classes to elements when referencing them. As a side note, this should also work with document.querySelector('.info').textContent = inputValue; as the <p> element is the only element with the info class, but since it specifically asked you to assign it to the <p> element with a class of info, I put the element name in the querySelector.
