trying to call the ID. what am I 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>

If you use .value you grab the text inside the input.

If you don't use .value you grab input form itself.

Hi. You are looking to grab the value so at the end you need to use .value:

var inputValue = document.getElementById("linkName").value;

Thanks for the clarification, but is ".value" needed go grab the Id using "document.getElementById()" every time? or only during <input> elements and forms?
