Hi,
You can't do that with a custom HTML module as it would require to process PHP code which a custom HTML module cannot.
You would need something like that instead
extensions.joomla.org/extensions/core-en...code-in-content/5051
And use such PHP code:
if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php')) return true;
$cartClass = hikashop_get('class.cart');
$currencyClass = hikashop_get('class.currency');
$cart = $cartClass->loadFullCart();
echo $currencyClass->format($cart->full_total->prices[0]->price_value_with_tax,$cart->full_total->prices[0]->price_currency_id);
