Uncaught SyntaxError: Identifier has already been declared

I want to make a modal-cookie thing where on page load, the modal checks if there is a cookie, and then if there is no "name" cookie, the modal will show. otherwise, the modal won't show. However, I have this error:

Uncaught SyntaxError: Identifier 'addCookie' has already been declared.

Because of this error, my cookies do not save.

I understand that this error happens when someone is trying to override a let. However, I didn't try to override it, I just tried to call it

<div id="modalWelcome" class="modal fade" data-backdrop="false">

    <input type="text" class="form-control" placeholder="your name" id="fname">
  </div>
  <button type="submit" class="btn btn-primary" onclick="addCookie()">go!</button>
</div>

if ($.cookie('name') == undefined) {
  $("#modalWelcome").modal('show');
} else {
  $('#modalWelcome').modal('hide');
}

var cookiename;
let addCookie = () => {
  cookiename = $('#fname').val();
  $.cookie("name", cookiename);
}

  1. Change onclick="addCookie()" to onclick="addCookie" because you need to set the handler, not execute.
  2. Check how your script is included because you could include it twice.
