Dom Scripting Challenge task 2/2

Hi I keep getting the error "You haven't called 'preventDefault' on the event object." for this task but can't seem to figure it out.

app.js 
const form = document.querySelector('form');
const submitButton = form.querySelector('[type=Submit]');

form.addEventListener('submit', (e) => {
  e.preventDefault;
})
index.html 
<!DOCTYPE html>
<html>
<head>
  <title>Submit Event</title>
</head>
<body>
<form>
  <label>Name:</label>
  <input type="text" name="name">
  <input type="Submit" name="submit" value="Submit">
</form>
  <script src="app.js"></script>
</body>
</html>

When you call a method, you must place parentheses after the method name even if no arguments are being passed:

  e.preventDefault();
