What am I doing wrong?

I have tried every way I can think of to solve this and treehouse is still saying it's wrong. What can I do?

app.js 
let inputValue = document.getElementsByTagName('a').textContent;
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>

Hi ! They ask for the value of the text input, not the link, you can then retrieve it thanks to its id :

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

That's weird, it worked for me :/ Are you sure you copied without changing anything ?

Hi Jackson. I can confirm that Johan has given you the correct answer for Challenge 1, I have copy/pasted as he suggested and it has worked for me.

So with Challenge 2, you should leave the answer to Challenge 1 in place and untouched, and one solution involves adding 2 more lines of code. I will just start them here...

let inputValue = document.getElementById('linkName').value; // leave untouched
let a = // follows a similar pattern to the line above, you must examine the html to find the id.
a.textContent = // what you defined in Challenge 1.
