Repeat total price at the bottom of one page checkout page

[shniurs]

Hi, I want to repeat the display of total price at the bottom of my order-opc page, so my customers could see the final price before clicking order button.

 

If I add this:

{displayPrice price=$total_price}

I get the price displayed, but if I make any modifications to the cart (add more products or choose different carrier) price at the top of page is refreshed while the second price at the bottom stays same unless I refresh page.

 

I know this is something to do with shopping-cart.js file, it updates the price inside shopping-cart-summary finding elements by id's, I've tried to add same js code just using new id's but it didn't worked.

 

Thanks for help!
