What I'm doing wrong?

Hi All,

I'm having issue solving challenge task 2 of 2. I tried to concat the two id element but no avail. Please let me know what I'm doing wrong?

Thanks, Lawrence

app.js 
let inputValue = document.getElementById("linkName").value + '. ' + document.getElementById("link").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>

Hi Lawrence, The task is actually asking you to set the text of the anchor to the value you stored in inputValue. So you need to get the value from the 'linkName' element, and set that to be the anchor's text - like this:

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

If you did want it all on one line, i guess you could do it like this, but its a bit messier in my opinion...

document.getElementById('link').innerHTML = document.getElementById("linkName").value;

Hope i was of some help :)

Hi Jake,

Thanks very much! I definitely miss innerHTML.
