Help adding another subtotal calculation

On the cart/order pages the subtotal is displayed by:
{include file="currency.tpl" value=$cart.display_subtotal}
{include file="currency.tpl" value=$order.subtotal}

How do I add another calculation for SUBTOTAL (call it) SUBTOTALGC?

ex.
subtotalgc, would take the subtotal and also subtract any ⌠discount/coupon■ that was submitted.

IF customer has:

subtotal = $20.00
disount/coupon = -$2.00

THEN

subtotalgc =$18.00

------------
so I would have an additional field created:
{include file="currency.tpl" value=$cart.display_subtotalgc}
{include file="currency.tpl" value=$order.subtotalgc}
------------

Re: Help adding another subtotal calculation

Something like this

Code:

{if $cart.discount_coupon gt 0}

 {assign var=display_subtotalgc value=$cart.display_subtotal-$cart.discount_coupon}

 {include file="currency.tpl" value=$display_subtotalgc}

{/if}
