How to withdraw the order amount?

Question

1C-Bitrix

Hello. There is a site 9ruk.ru, there is "Suma" in the header on the right. This is text for now.
How can I bind a variable here?
Here's what happened before:

<div class="foot_panel_2">
  <?$APPLICATION->IncludeComponent("bitrix:sale.basket.basket.line", ".default", 
    array(
      "PATH_TO_BASKET" => SITE_DIR."personal/cart/",
      "PATH_TO_ORDER" => SITE_DIR."personal/order/make/",
      "HIDE_ON_BASKET_PAGES" => "N",
      "COUNT_DISCOUNT_4_ALL_QUANTITY" => "N",
    ),
    false,
    array("HIDE_ICONS" => "Y")
  );?>								
</div>

But it was in the footer, a lot of extra stuff. And I need only 1 number - the amount of the order.

<?php

// Include Sale module 
Bitrix\Main\Loader::includeModule("sale"); 

// Query: Get all cart items for current user
$res = CSaleBasket::GetList(
  array(),
  array(
    "FUSER_ID" => CSaleBasket::GetBasketUserID(),
    "LID" => SITE_ID,
    "ORDER_ID" => NULL,
    "CAN_BUY" => "Y"
  ),
  false,
  false,
  array(
    "QUANTITY",
    "BASE_PRICE",
    "PRICE",
    "DISCOUNT_PRICE"
  )
);

$totalPrice = 0;

// Temp array with cart items
$arItems = array();

// Fetching query
while($arFields = $res->Fetch()){
  // Check for base price
  if(!isset($arFields['BASE_PRICE']) || (float)$arFields['BASE_PRICE'] <= 0){
    $arFields['BASE_PRICE'] = $arFields['PRICE'] + $arFields['DISCOUNT_PRICE'];
  }
  
  // Calculate total price without discount
  $totalPrice += $arFields["PRICE"] * $arFields["QUANTITY"];

  $arItems[] = $arFields;
}

// Make array for discount calculation
$arOrder = array(
  'SITE_ID' => SITE_ID,
  'ORDER_PRICE' => $totalPrice,
  'BASKET_ITEMS' => $arItems
);

// Checking for authorized user
if(is_object($GLOBALS["USER"])){
  $arOrder['USER_ID'] = $GLOBALS["USER"]->GetID();
  $arErrors = array();
  // Calculate discount
  CSaleDiscount::DoProcessOrder($arOrder, array(), $arErrors);
}

// All done!
echo $arOrder['ORDER_PRICE'];
