Not sure what else to do w/ document.getElementByID('linkName')

I am not sure what to do. This seemed like it would work by using the ID name to get the element input.

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 Karly,

You are almost there. The challenge is asking to assign the value of the input element to the inputValue variable.

document.getElementById('linkName')

would return the input element and its attribute

<input type='text' id='linkName'>

In order to return the input value you have to add .value at the end of what you had before.

document.getElementById('linkName').value

I hope that helped.

You want the value from the input so you need a .value at the end. There is a link from the challenge to a video that explains

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