Confirmation of information on checkout steps

Hi, I have a checkout process consisting of 3 steps: address, payment and confirmation. I'm building a custom template with templates also overriding hikashop's.

The things is I need to display on each step the information entered from previous step. That is, in step #2 (payment) I need to display the address entered, and in the step #3 I need to display the address from step #1, the payment info from step #2 and the cart total.

How can I get this information on other steps?

-- url of the page with the problem -- : mywebsite.com/mypage
-- HikaShop version -- : x.x.x
-- Joomla version -- : 3.2
-- PHP version -- : 5.5
-- Browser(s) name and version -- : XXXXX x.x.x
-- Error-message(debug-mod must be tuned on) -- : Error_message
