Hi Otis -

To answer your second question first:

> Total and print it at the end of the cart, just once. No [perl]?

You have to return an empty string from [perl] or [calc] tags if you don't
want anything showing up in the browser:
   [perl]
      ... your code ...;
      '';  # return nothing
   [/perl]


The [calc] tags will retain values within a page, so you should be able to
change this: 

> [if items] [then] [item-list]
> [sql type=list query="SELECT our_retail_price
> FROM product_term WHERE term_id = '[item-code]'"]
> 	[set our_retail_price][sql-param our_retail_price][/set]
> 
> 	[set total-price]
> 		[calc][scratch total-price] + [scratch our_retail_price][/calc]
> 	[/set]
> 
> [/sql]
> [/item-list][/then][/if]
> 
> Total: [scratch total-price]

to this:

   [calc] $total = 0; ''; [/calc]
   [if items]
      [item-list]
         [sql type=list query="SELECT our_retail_price
                      FROM product_term WHERE term_id = '[item-code]'"]
            [calc] $total += [sql-param our_retail_price]; [/calc]
         [/sql]
      [/item-list]
   [/if]
   Total: [calc] $total; [/calc]
