Installment widget - Wordpress + Woocommerce

Question

What's the problem? I want to add a PayU plugin installment widget for a product subpage for WooCommerce, but I have a problem with displaying the product price in the calculator provided in the documentation.

Code source for implementing such a calculator:

https://developers.payu.com/en/installments.html#installments_best_practices_mini

<p><span id="installment-mini"></span></p>
<script type="text/javascript">
  var value = 1234.56;
  if (value >= 300 && value <= 50000) {
      var options = { 
          creditAmount: value,    // amount in PLN 
          posId: '67328',         // point of sale identifier 
          key: 'zQ',              // first two characters of API key
          showLongDescription: true 
      }; 
   
      OpenPayU.Installments.miniInstallment('#installment-mini', options) 
      .then(function(result) { 
          // This fragment of code will be executed after widget is shown  
          // parameter ‘result’ contains additional functions
      }) 
      .catch(function(e)  { 
          console.error(e.toString()); // This snippet writes config errors
          // to developer’s console
      });
  }

What do i want to get? I want only the product price in the product card to be downloaded to the installment calculator. There is no input field in the product card, only , I thought about a positive in the php code but it did not work. I want to add a regular price or the price of a product variant to the JS code to show the customer what he can do when choosing installments, so the price must be taken to the code above.
