In fact, you first have to select the input so just : let inputValue = document.querySelector('input'); Then, you need to change the <a> so create a new variable that store a : let a= document.querySelector('a'); FInally, store the inputValue into the a variable like this : a.innerHTML = inputValue;

That´s not correct, please read the task. It says in step 2 to change the value of the variable which you created in step 1. If you do so, the error is "can´t pass task 1".

Please, treehouse - Team, start to make the tasks clearer! It happened a few times now that a lot of people don´t really get the challenges tasks.
