Display of the discounted price

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.1.5

The display of my product page with the discounted price is:

65,00 €55,25 €

I would like to have it like this:

65,00€
55,25€

How can I do this?

And how can I have it like this?

65,00€
-15%
55,25€

Thanks

Ok, thanks

Now I have the "listing_price" like this:

if(!empty($this->row->discount)){
if(true){
echo '<span class="hikashop_product_discount">'.JText::_('PRICE_DISCOUNT_START');
if(bccomp($this->row->discount->discount_flat_amount,0,5)!==0){
echo $this->currencyHelper->format(-1*$this->row->discount->discount_flat_amount,$price->price_currency_id);
}elseif(bccomp($this->row->discount->discount_percent_amount,0,5)!==0){
echo -1*$this->row->discount->discount_percent_amount.'%';
}
echo JText::_('PRICE_DISCOUNT_END').'</span>';
}if(true){
echo '<span class="hikashop_product_price_before_discount">'.JText::_('PRICE_DISCOUNT_START');
if($this->params->get('price_with_tax')){
echo $this->currencyHelper->format($price->price_value_without_discount_with_tax,$price->price_currency_id);
}

But it is not working, the product page it's still showing:

120,00 €
102,00 €
