Stumped on Code Challenge. getElementbyId

I can't figure out why this is not the correct answer, the code challenge is:

"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."

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>

Hi Thomas! Just a typo. Inside the getElementById the "B" letter is started to uppercase .
