Can't declare second variable.

Receiving error message on Step 2 ( Are you using the method that targets an element by its ID?) What's wrong with my code ?

app.js 
var button = document.getElementById ( 'btn-phrase' );
var input = document.getElementById ( 'input-phrase' );

button.addEventListener('click', () => {
  alert(input.value);
});
index.html 
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <title>Phrase Sayer</title>
  </head>
  <body>
    <p><label for="input-phrase">Type a phrase</label></p>
    <p><input type="text" id="input-phrase"></p>
    <p><button id="btn-phrase">Say Phrase</button></p>
    <script src="app.js"></script>
  </body>
</html>

Your code is fine, but you have unnecessary spaces that are confusing the checker. It will pass the challenge if you change var input = document.getElementById ( 'input-phrase' ); to var input = document.getElementById('input-phrase');
