Hi,

You just need to use 'innerText' to set the text content. This will work for you:

<!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>

        <button type="button" onclick="setText()">Set link text</button>


        <script>
        function setText() {
            let inputValue = document.getElementById('linkName');
                document.getElementById('link').innerText = inputValue.value;
            }
        </script>
    </body>
</html>

just do this in index.html

let inputValue=document.getElementById('linkName').value;
let link = document.querySelector('a');
link.textContent = inputValue;
