That wouldn't work per the request, as the request stated that the information was to be sent upon the Enter/Return key being pressed.
Using the edit event, per your code, would have the information displayed in 3 being changed simultaneously with the information being changed in 4. The edit event doesn't wait for the Enter/Return key to be pressed before the rest of the event is completed, but completes all of the commands for every keystroke in the edit ID.
