Call a function on another card

[Bob Sneidar]

When I encounter situations like these, I begin to ask myself why the handler is in a card script. If it needs to be accessible from other cards, it should probably be moved to the stack script, or put into a button and inserted into front or back. I have 3 buttons I use for this effect: Utilities, Validations and Database Functions. Utilities and Database functions I insert into back. The validations I insert into front in case I want to intercept things like openField or selectionChanged and do things before passing them on.
