Simple Variable Question

[updmike]

I am trying to instal a affiliate program that will calculate a percentage of the subtotal of the order.

 

I've been looking throught the includes and main php but cant seem to find a variable for sub_total..

 

Is there a list of all the variables used in OsCommerce

 

Does anyone know the var for the subtotal?

 

Thanks very much.. :?:

$currencies->format($cart->show_total());

yes, but that will only affect the display of the amount, not the actual amount. depending on what you want to do, you'll probably have to dig around the shopping_cart class to get at the actual amount.
