I don't understand this question, what they're asking for.

I'm sorry I can't specify better than that. This is the question: "Select the button with the ID sayPhrase and assign it to the button variable."

js/app.js 
var button;
var input;

button.addEventListener('click', () => {
  alert(input.value);
});

button = document.getElementById('sayPhrase');
index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Phrase Sayer</title>
  </head>
  <body>
    <p><input type="text" id="phraseText"></p>
    <p><button id="sayPhrase">Say Phrase</button></p>
    <script src="js/app.js"></script>
  </body>
</html>

Hey Michele, So this step in the challenge just wants you to assign the button variable in your JavaScript to the sayPhrase ID from your HTML page.

It would look like this:

var button = document.getElementById('sayPhrase');

Hope this helps!

Hey Michele,

You actually did it correctly except, they want you to assign it to the variable they provided, when its declared on line 1, and same on line 2 for next task
