Our last consultant gave us source codes but they are encrypted! All we need to do is to capture a displayed data (in this case a total amount) and change one condition such as (if the total amount is greater than YYY then display a warning message). Because the condition is hard coded (in encrypted files), we thought we can use trigger(s), whcih can capture the total amount and to apply it with the new condition coded in the trigger(s).
Thank you again for your help.
