Error line 242 in discount.php

Hi there,

Using Hikashop 2.1.0, under Joomla 2.5.9 - when I setup an auto-coupon with these parameters:

Code : BUYING3
Type: Coupon
Published: Yes
Minimum order value: $ 45.00
Minimum number of products: 3
Auto load in cart if possible: Yes

[ for $ 3 off if a customer buys 3 products [all products have the same price], ]

On the front end, I get:
Warning: Invalid argument supplied for foreach() in /home/cridge/public_html/administrator/components/com_hikashop/classes/discount.php on line 242

I have since then turned off this discount when I realized that the auto-loading of coupons on works at the product level
and NOT at the item level and therefore won't work for me. BUT I figured I'd still mention it!

Cheers,

Emmanuel.
