Right method, wrong tag.

You're getting the value the right way, but you're selecting the element with an ID of "link", which is the anchor (link) element. But the instructions asked you to select the text input element instead (which has an ID of "linkName").

Well, you know how to select that element (it was the one you had selected by mistake last time). But instead of the value property, this time you want the textContent property. Other than that, it's just swapping the sides of the assignment.

Remember what I said about "swapping the sides of the assignment":

document.querySelector('#link').textContent = inputValue;

are we swapping the sides of the assignment because we are reassigning a new value to the variable? and if so would it work normally if u didn't swap

In an assignment, the thing being assigned goes on the left side.

In task 1, you assigned the variable, so the variable name is on the left side of the equal sign.

But in task 2, you are using the value that you stored in the variable to assign the text content of the "a" element. So the variable name goes on the right side of the equal sign.
