What is wrong with my code and How to show new price for Woocommerce item?

Question

WooCommerce

I want to show the new price of an item. I wrote a code where there are conditions, and if they are true, they will return an arbitrary php template.
Here is the code:

function laminate_get_price($price, $product) {
   global $post, $woocommerce, $product;	
  
       $active = get_post_meta($post->ID,"_calculatorscript_active",true);
  
    if($active != 'no' && $active != NULL) {
    $calculatorValue = get_post_meta($post->ID,"_calculatorscript_value",true);
      require_once 'new-price.php';
    }
return false;
    }
  
   add_action('woocommerce_get_price', 'laminate_get_price', $product, 2);

Template code:

<p class="price">
  <span class="woocommerce-Price-amount amount"><?php echo number_format((get_post_meta($post->ID,"_regular_price",true) / $calculatorValue),2,",",""); ?> <?php echo get_woocommerce_currency_symbol("UAH"); ?> </span></p>

On the page I see the new price, but up to the content of the product and with some problems. What's wrong with the code?
If I use woocommerce_get_price_htmlthen all prices disappear except for the one on the product that meets the conditions.
