How to display total order minus an amount?

[invasi0n]

Hi,

 

I would like to know how can I display somewhere on account_history_info.php an amount that represents the total order minus other amount. Let's say the total order amount is 50 and I'd like to display, somewhere on that page, 30. How can I do that?

Or how can I display the total amount (on account_history_info.php) without the currency symbol? I see that $order->info['total'] gives the total amount including the currency prefix, but I need just that number without currency and <b></b>.

 

Thanks.

Nobody can tell me how do I extract the total order amount from database?

 

Thanks.
