Hi, I don't know what's wrong with my variable when I type in the following

var inputValue = document.getElementById('linkName');

app.js 
var inputValue = document.getElementById('linkName');
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 Johannes,

You've selected the element correctly, but the challenge asks you to go one step further:

Select the <input> element with the ID linkName and store its value in the variable inputValue.

The wording can be a little confusing -- they're not asking for the element itself, but instead they want the text that has been input to the field. For a refresher you can check out the linked video starting at 3:30. The teacher's notes for the video also have a useful snippet under the heading "Accessing the value of an input element".

I hope this helps! Let me know if you run in to any trouble.

Hi Cameron,

thanks so much for your help, it worked now after some trials and errors. The second one is also quite tricky and I spent already a lot of time on it, but I'll keep trying!

Hi Eugine, if you read Cameron's explanation, then he writes about the teacher's notes below the video that he recommends. Try to follow what's written in the snippet, then you'll see, that it works. I hope that helps.
