Javascript and DOM work problem

Idk what I'm doing wrong I don't understand the directions and I have literally tried anything I can to make this work.

js/app.js 
const sayPhrase = document.getElementById(sayPhrase);
var button;
var input;


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

You're close, but I see two issues:

  • the ID name must be enclosed in quotes when passing it to getElementById
  • the instructions say "assign it to the button variable", but this code assigns it to "sayPhrase" instead
