In shopping car, the program needs to be extended to ;

1. A feature to limit purchasing order number from customers on paticular product. This purchasing order number is instantly subtracted to stock number. So the customer do not order the product more than what we have in store. (the current program brings the shopping order to payment steps straight away, this will consequently cause problem to refund customer when there is actually no product left in stock)

2. Then when the product is out of stock, the pop up window shows ' Out of stock' or 'not available'.

Kindly add these features soon, our business is running and we need them.
