I want to display an HTML [popup] box that displays the Grand Total of a Ticket in a POS.The SQL Script is very basic.select Grand_Total from Invoice_Totalswhere Payment_Method = 'CA'So, if the SQL line that is updated has Payment_Method = 'CA', then display Grand_Total in a nicely formatted HTML box (or similar)So the premise here (Use Case) is when the merchant rings in some items at his store, and the customer is paying in CASH (Payment_Method = 'CA') then display a Text/HTML box with [Grand_Total] when the line in the SQL Table Invoice_Totals is updated and Payment_Method = 'CA'Thank you to all in advance.
