Hi, every time we open the view_bill screen (clients screen) and we begin to add products to the POS list; there´s no immediate update into the view_bill screen, also when we add two or more products the bill doesn´t add more products it only show the first item. I tried replacing the modified file to the SMA´s stock file also didn´t work. POS works perfectly, but I can't find a way to coordinate the POS sale with the customer's screen; so that the customer sees in real time what is being charged.
