ReferenceError: Can't find variable: input

Ive inserted the code: const inputValue = document.querySelector( input );

And I keep getting the error message: ReferenceError: Can't find variable: input I've tried various different ways and I keep getting different error messages. I simply fail to see how to continue with this task in a way that differs enough from this. If Im doing something wrong please tell me, because I have no Idea what to do now.

app.js 
const inputValue = document.querySelector( input );
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>
    <script src="app.js"></script>
  </body>
</html>

There are 2 issues with your code. First, querySelector takes a string as a parameter, and input without quotes around it makes it a variable, so to select an element you want:

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

I'll point out that the challenge asks for the value of the input element, so you'll have to pull that afterwards, or you can do it in the same statement with:

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

Thank you so much! I had actually previously tried "const inputValue = document.querySelector('input');" , and yet, I still got the error message: "ReferenceError: Can't find variable: input" so I resorted to the other one. Never did the error messages mention value(I know that the instructions mentioned it, but I found it weird how the error didn't say anything).I think theres some refining to do for the error messages, they are somewhat confusing in this task.

When I do const inputValue = document.querySelector('input');, I get the error: Bummer: Make sure that you get the value of the selected 'input' element. This goes to the 2nd point in my answer about pulling the value at the same time.
