website/pinnacle cart help

I run a site crownsuspension and was wondering how to add a field to my product page. I am unsure what that code is but this code will pull shipping weight from the product info but I need a new line to say estimated shipping and full the data from the product info estimated shipping price that i filled in on the product using their cart.

or
I think this might be easier.

we can add a new line below weight and have the new line say estimated shipping $XX.XX(2 times the weight)


I have trying playing with this code but i am not sure what language it is.

here is what i am looking at and this is the page its on got to crowmsuspension and navigate to any product. sorry cant posts urls

{if $ShippingShowWeight == "YES"}
<div class="product-weight gap-bottom {class file=$smarty.template editable=true}">
{if $product.free_shipping == "Yes"}
{$msg.product.weight}: {$msg.product.free_shipping}
{elseif $product.weight> 0}
{$msg.product.weight}: <span id="product_weight">{$product.weight|weight}</span>
{/if}
</div>
{/if}

any help would be great i alwas do research and not scared of work but i don't know what the language is so very little i can do right now.
