Templates - how do I edit the "details" layout in
 

My problem always seems to be the same... not being able to find the right template to edit. Is there a comprehensive breakdown somewhere, or are there just too many possibilities to document?

What I am trying to do now is my product "details". I added a couple of new fields so I have three separate items in "details" and they all scrunch together, with the price pushed up hard against. I need to put some space between these items. Where is this template?

this is customer/main/product.tpl

There used to be a template tree that was part of the support files, not sure if it exists now.

You could always switch on debug in general settings and it will tell you which templates it has used to create the page seen on the screen.
