I have 2 lightbox (modal) :

Sign up modal box

  import wixWindow from 'wix-window';
  import wixUsers from 'wix-users';
  import window from 'wix-window';
  import wixUsersBackend from 'wix-users-backend';

  let email
  let password

  //...Enter his email & password 

  wixUsers.register(email, password)   // add email & password to database
     .then( (result) => {
      wixWindow.openLightbox("Conditions générales de vente"); // after adding to DB, displaying "condition & terms" modal(lightbox)
  if(accept.clicked == true);              // if user accecpt terms...
    let status = result.status;   // ..."Pending" the result
  else{
    let user = wixUsersBackend.currentUser;
    wixUsersBackend.deleteUser(user .id)      // delete the current user registration on DB
       }
   } );

Condition & terms

  import wixLocation from 'wix-location';
  import window from 'wix-window';
  import wixWindow from 'wix-window';

   $w.onReady(function () {
      $w('#button1').onClick(() => {
       let accept   // button have "accept" variable 
       wixLocation.to("/home"); // redirect to home page
         
         });
       
       $w('#button2').onClick(() => {
          window.lightbox.close();
          });
     });

I missing something in the script? Could anyone help me with this.
