Using "points" (with no cash value)

Hello,

I'm setting up my store to use 3 kinds of products:
- products with a price (in USD)
- free products
- products that "cost" points (which have no cash value)

My shop is set up to use USD as the main currency. This also works for free products. However, I'm running into 2 issues with products in the third category:
- Product "prices" are displayed like "$0.00 (5 Points) each". I'd prefer to have the products displayed as "5 Points each".
- Recently, the page shows the following error on load. While it's an error that makes sense, I think it's only come up after upgrading Joomla to 3.2 (though I can't confirm that is the cause, I do know that it was not showing that error earlier). It seems to display it once for each product in the current category.

Warning: Division by zero in /var/www/vhosts/[redacted]/administrator/components/com_hikashop/classes/currency.php on line 734

My line 734 is the same as yours:

$prices[$k2]->taxes[$k]->tax_amount= $prices[$k2]->taxes[$k]->tax_amount/floatval($srcCurrency->currency_rate);

I'm sorry; I'm not sure I understand. It seems like you are saying to change my currency rate inside of HikaShop to something other than 0. Doing that does get rid of the divide by zero error, but that doesn't give me a way to have these items display in only the points currency--it instead shows an item as (for example) $5.00 (5 Points).

Is there something that I should change in currency.php?
