Sorry for the confusion MC12345678.
I've been trying to get the module working from the start, it only seemed to output the correct page type, with the product ID and product price not working.
I've managed to get it working for the product page with hard-coding amendments, but the cart page is still outputting the product ID rather than the model number that matches what we have in Google Adwords already set up (product feeds and campaigns).
Doing what I've done on the product page on the cart page doesn't work, for whatever reason. Another added issue is that I need the cart page to add up all the product prices together, and have all the model numbers listed and separated by a comma - which in fairness it is actually doing correctly. So if I could fudge the 'product_id' element for 'product_model' then this would give me what I need.
Sadly I'm not an expert coder, and I admit I'm struggling to get the module to do what I want. The dev abandoned it a while ago I think which is a shame as the remarketing element of Google Adwords is ideal for e-commerce stores and I can't believe that there aren't more people / stores on Zen wanting this module.
Thanks for your help so far, it is much appreciated.
