The first part is asking to get the value from the element. you have the element, but to access the value you can you the value property of the element.

let inputValue = document.getElementById('linkName').value;

Now that you have the value stored, it asking you to change the text for the a tag. That tag has the id of 'link', so you can use the getElementById function to get the element. Then you can access the text of the element with the innerText property.

document.getElementById('link').innerText = inputValue;
