The point of the last instructions was to see if you did configured this option since, yes, it is relevant. Opencart validates the minimum quantity and included in my code modifications above along with the product option value quantity. If the defined value for the minimum quantity in the admin is already configured, that's fine since most merchants may oversee this step.Product min qty is set to 1. But isn't that irrelevant? Product qty is 12. All qty options add up to 12, both product and options subtract stock. So it's correct as far as I can see.
The minimum main product quantity would be 1, that is correct. What my modifications above provides is if the main product quantity is higher than the product option value quantity, that wouldn't fit the scale so it provides an error message on the products page, in this case.A product may have one option with qty of 2 and one option to with qty of 5. That's a total of 7 for main product. Min qty for main product would be 1?
