Hi Patrick Shangala ,

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

/***
https://developer.mozilla.org/en-US/docs/Web/Events/submit 
Note that submit is fired only on the form element, not the button or submit input. (Forms are submitted, not buttons.)

So you'll need for change that addEventListener to listen on the 'form' not the 'submitButton'
You'll also need to listen for 'submit' not a 'click'
And lastly, to use the event (e) in your function, you'll need to pass it through 
***/  

submitButton.addEventListener('click', () => {
  e.preventDefualt();
});

I could write out the code but I hope that helps you more.
You're getting there! Keep up the effort :smile:

Happy coding,
Dave :dizzy:

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

form.addEventListener('submit', (e) => {
  e.preventDefault();
});

Good luck ... you're going to need it.
