It keeps saying this is not correct. I can't figure out what I'm missing here.

I believe the code is correct, but maybe i'm missing something here.

js/app.js
let button = document.getElementByID('sayPhrase');
let 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>

Sorry, I forgot to add the question.

There is a variable named button in app.js. Set its value to contain a reference to the button element in index.html with the ID of sayPhrase.

oh man, you are so close!! and I mess up this way all the time, I even had to double/triple check your code to see what was wrong because it looks fine!

but remember JavaScript is case sensitive.

getElementByID is not the same as getElementById

so just make sure the letter d in Id is not capitalized
