I posted this on another forum, but this appears to be the help thread for this contribution. I spent hours installing the Price Break Contribution and it appeared to be working fine, as far as "looks": http://familymemoriesandmore.com/cart/prod...;products_id=28
However, when I change the quantity and add to cart, it only adds 1, 2, 3, 4, etc., according to how many times I've tried! Then if I change the quantity while in the cart, I get this error:
Fatal error: Unsupported operand types in /home/garysgal/public_html/cart/includes/application_top.php on line 355
Here's my line 355 in my application_top:
$cart->add_cart($HTTP_POST_VARS['products_id'], $cart->get_quantity(tep_get_uprid($HTTP_POST_VARS['products_id'], $HTTP_POST_VARS['id'])) + $HTTP_POST_VARS['cart_quantity'], $HTTP_POST_VARS['id']);
I have a discount coupon codes contribution installed already and working great. I thought I could install the CCGV contribution, but apparently they will conflict. I've done searches on the contributions and can't find one other than the CCGVs... any suggestions for me? Obviously I want to keep a running balance, I don't want clients to have to use their entire balance, etc...
