[solved] display two prices in list product

As the subject, I need to show the full price and the discount price in the list product (not only in the product page)...
I didn't find the options, or I didn't understand how it works...or I have to chage the php files?
Help, thanks

thanks for your answer..I tried all the options in the menu "show discount price" but in the frontend I have only the lower price...
in the first attachment image you can see my options...I don't find "show both price"
in the second image you see the two price I have to show, "prezzo al dettaglio" full price and "prezzo", in the right menu as the discount price

(sorry for my bad english......)

Hi,

You can edit the view "product / listing_price" and remove: && JRequest::getCmd('layout') == 'show'
in the two if conditions: if(isset($this->row->product_msrp) && @$this->row->product_msrp > 0.0 && JRequest::getCmd('layout') == 'show' && $this->params->get('from_module','') == ''){

It works!!! Thank you so much!!
