Hello
I would like to modify (or create new) design page for product. I have design 1/2/3/4/5 but i need to make simple modifs like untabbed (descrioption/review) and add some external data from a database.

How can i modify (create) a new design of the product page?

in product.tpl you have

slotStart(‘product/product.product_reviews_summary’, array(‘data’ => $data)); ?>

CONTENT HERE

slotStop(); ?>

How can I add a “slot” or modify a design?

Thanks.
