I don't understand this question Select the <input> element and assign its value to the variable inputValue

... app.js

const input = document.querySelector('sample-text')

...

app.js 
const input = document.querySelector('sample-text')
index.html 
<!DOCTYPE html>
<html>
    <head>
      <title>DOM Manipulation</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
      <div id="content">
        <label for="linkText">Link Text:</label>
        <input type="text" id="linkText" value="sample text">
        <p class="info"></p>
      </div>

Try changing your variable name from input to inputValue.

You also need to find a way to select the element. I think what might be happening is you're trying to find an element of a particular ID. But since it's querySelector you're using you'll need to provide the # for an ID as if it was a CSS Selector.

And then at the end, make sure you're grabbing the value of the element you're selecting.

Either of the following should work. 

const inputValue = document.querySelector('#sample-text').value;

const inputValue = document.querySelector('input').value;
