Is it possible to use a command string to update a specific textbox within the data card, picking up two values from two other textboxes and then show the result in the 'result' textbox?
Example. I have one textbox called 'Cost'. I have two others: 'A' and 'B'. I want to get the values from 'A' and from 'B', perform an equation, and show the result in the 'Cost' textbox at runtime.
