yes, it is possible to add 5 products,
i haven’t set the blocks for the second to fifth products,
it is possible to add price, just press the violet cart button,
then if quantity is zero, out button is disabled,
but if the total due that are going 'IN" is greater than the cash, it will not be processed.
the problem is, when i add quantities that are going in or out, the cash and quantity added get doubled…
example if, there are 10 available items and cash is 100, when i add 5 more items with the price of 1 each.
the outcome is 20 available items and the cash will be 110… when it is supposed to be just 15 items and 105 cash…
after i am satisfied with the blocks on shelf A product 1, the next shelves will be okay too… that;s why im focusing on this one first… but no matter what i do, it still wont work, and sometimes it gets worse.
