Im using document.GetElementById('') It is telling me that i'm getting undefined... what is this questioning asking?

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

I don't understand what's wrong

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>

Put 

button = document.GetElementById('sayPhrase');

before the

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