How to collapse user input fields based on paid plan

Hi all,
I want to give the account owner a certain amount of input fields based on the paid plan he/she purchased.
Plan 1, only one input field (container box); Plan 2 , two input fields and so on.
I am a complete beginner at coding but tried the below, unfortunately it seems that the connection to the Plans database is not working and at the last line I receive an unexpected token error.

Can somebody help me, please?

Thanks so much in advance,
Patrick

import wixUsers from 'wix-users';
import wixData from 'wix-data';
import wixLocation from 'wix-location';
import wixPaidPlans from 'wix-paid-plans';

$w.onReady (function () {  

// Call getCurrentMemberOrders() to get the current plan information the logged in user has pruchased
  wixPaidPlans.getCurrentMemberOrders() 

    wixUsers.currentUser.getWixPaidPlans()
    .then( (WixPaidPlans) => {
 let slug = slug;                        // "1-plan"
 

// Based on the "slug" of the paid plan purchased, I want to show/hide container boxes. If the account owner purchased "Plan1" (Slug is "1-plan"), all container boxes (2-5) should be hidden, if "Plan2 " as purchased, container box 2 should be available but 3-5 hidden and so on. 

 let value = $w("#slug");
 if (value === "1-plan") {
    $w("#box2").collapse();
    $w("#box3").collapse();
    $w("#box4").collapse();
    $w("#box5").collapse(); 

        } else if (value === "2-plan") {
        $w("#box3").collapse();
        $w("#box4").collapse();
        $w("#box5").collapse();
 
            } else if (value === "3-plan") {
            $w("#box4").collapse();
            $w("#box5").collapse();

                } else if (value === "4-plan") {
                $w("#box5").collapse();
 
 //If "Plan5" was purchased, all container boxes should show.
                  } else {
 
          }
 
  {
 
});
