I don't know what's wrong with this code

Task: Next, declare a new variable named input. Point the variable to the input element with the ID input-phrase. Use the method that returns an element matching the specified ID.

I was not able to pass this task and don't know what's wrong with my code.

app.js
// Complete the challenge by writing JavaScript below
const button = document.getElementById ('btn-phrase');
const 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>

Hi Chiaki. What you have is correct but for some reason the challenge is being picky and not allowing a space between the method call and the parameter being passed. Delete the space and it should pass. Weird that it allows a space on the first one.

const input = document.getElementById('input-phrase');
