В корзину товар с детальной не добавляется. Вот такой код...

Подскажите куда копать?

<div class="product_row_content">
<h1><?= $arResult['NAME'] ?></h1>
<ul class="product_row_content_props">
<? foreach ($arResult['DISPLAY_PROPERTIES'] as $PROPERTY) { ?>
<li>
<strong><?= $PROPERTY['NAME'] ?>:</strong>
<? if (is_array($PROPERTY['VALUE'])) { ?>
<? echo implode(', ', $PROPERTY['VALUE']) ?>
<?
} else { ?>
<?= $PROPERTY['VALUE'] ?>
<?
} ?>
</li>
<?
} ?>
</ul>
<div class="product_row_content_actions">
<?
foreach ($arParams['PRODUCT_PAY_BLOCK_ORDER'] as $blockName) {
switch ($blockName) {
case 'price':
?>
<div class="product_row_content_price" id="<?= $itemIds['PRICE_ID'] ?>">
<?
foreach ($arResult['ITEM_PRICES'] as $ITEM_PRICE) {
echo $ITEM_PRICE['PRINT_BASE_PRICE'];
}
?>
</div>
<?php
break;
case 'buttons':

<div class="product_row_content_btn" data-entity="main-button-container">
