Regarding the fact that the product gets added to the cart when the checkbox is not ticked, looking at your screenshot, that's normal. It's just that you didn't tick the checkbox in the "For the value". After doing so and saving, it should work like you expect.

Please change the code: Code: $value = explode(',',$value); return parent::display($field,$value,$map,'checkbox',$inside,$options,$test); to: Code: if(!is_array($value)){ $value = explode(',',$value); } return parent::display($field,$value,$map,'checkbox',$inside,$options,$test); in the file administrator/components/com_hikashop/classes/field.php and the code: Code: }elseif($value == $field->field_options['product_value']){ to: Code: }elseif(is_string($value) && in_array($value,$field->field_options['product_value'])){ $ok = true; }elseif($value == $field->field_options['product_value']){ in the file administrator/components/com_hikashop/classes/cart.php and that should fix the problem.
