Hi can anyone help me with an error message I get when someone logs in to my store.The message is. ... " Fatal error: Unsupported operand types in /home/cuddlesn/public_html/cuddlestore/includes/classes/shopping_cart.php on line 763"

Line 763 on shopping cart.php reads as follows: $attributes_price += $attribute_price;
