I don't understand what I'm doing wrong

Select the input element with the id of "linkName" and store the value into the variable inputValue.

I assumed that you would use getElementbyId() but i don't know what I'm doing wrong

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>

You don't use a # in getElementById, just the id name in quotes

When selecting element with getElementById method, you don't need to write hash or pound sign '#'

Here is the code:

var inputValue = document.getElementById('linkName').value;
document.getElementById('link').textContent = inputValue;
