fetch page values dynamically?

<div> someone just deleted my question but didn't say why
I was wondering if someone could point me in the right direction.  We are running an .NET e-commerce website via nopCommerce 3.5 and would like to enable google remarketing code fully.  We included the google remarketing code BUT it is static - i.e we put it in on the header of the site and it works - its in every page BUT it is hard coded and refers to a single item on our site.

I am trying to work out how to make the remarketing code Dynamic.  I.e each page would fetch its own values dynamically via .NET or SQL.  

Google remarketing code is looking for :
1)ecomm_prodid: 'REPLACE_WITH_VALUE',     (I think this is a product id) 2)ecomm_pagetype: 'REPLACE_WITH_VALUE', (I think this is page type) 3)ecomm_totalvalue: 'REPLACE_WITH_VALUE', (I think this is total value)

How would I get each product page ...
