help me understand...

I’m trying to make customizations to the code, and one thing I don’t understand is how/where it reads in select fields.

For instance in admin/products_pages/products.tpl around line 72 is says:

but if I want to swap out the $product.list_price with the shipping cost (as referenced on other pages like products_updates.tpl, as $product_data.shipping_freight) it doesn’t read the amount in.

Is there a read statement or how can I get variable amounts to show that may be in other mysql tables? Hope this is clear.
