I have tried several ways with no luck. Please help me. I keep trying to reset the querySelector to the anchor.

I cant seem to attach the anchor value.

app.js 
let inputValue = document.querySelector('#linkName').value;
index.html 
<!DOCTYPE html>
<html>
    <head>
        <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <div id="content">
            <label>Link Name:</label>
            <input type="text" id="linkName">
            <a id="link" href="https://teamtreehouse.com"></a>
        </div>
        <script src="app.js"></script>
    </body>
</html>

It may be easier to use getElementById instead of querySelector

Still no luck at all. I try selecting the link and div id and it says I selected an element but not the right one.

Are you including the #? One solution for the first task:

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

So you are trying to get the value of the input element and then set it to the HTML of the anchor, right? If so, to select the anchor you have to do the following:

document.querySelector("a").innerHTML = inputValue;

Try textContent instead of innerHTML
