In the canteen/shop management system, parents are currently able to order uniforms without selecting a size. The sizes are listed as options in the bottom section of each item, however the system still allows orders to be processed and paid for without a size being chosen. This is a significant issue, as it results in incomplete orders and creates confusion during fulfilment. Could we please make the size selection a mandatory field so that parents are required to choose a size before they can proceed to checkout?
