Why it can't work

It keep showing the Bummer: You need to select the 'input' element, and store its value in the variable 'inputValue'.

app.js 
var inputValue = document.querySelector("input#linkName").value;

inputValue = document.querySelector("a#link").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>

On the first line, you created and assigned the "inputValue" variable.

On the next line, instead of assigning it again, you will be using it as the source of an assignment that will store its value into the element's text content. So you're close, but you have the left and right sides of the assignment reversed.

Also, when using ID's as selectors, you don't need to combine them with the tag name, since the ID must be unique on the page.
