Just slap a big red 'INVALID' button on there and call it a day. Who needs fancy validation components when you've got good old-fashioned shame and embarrassment?
Hmm, I'm not so sure. C) Calculation could be useful for some advanced validation, and A) Messaging might be good for communicating the results to the user. This one's a thinker!
I think B) Alert and D) Formula are the way to go. Alerts can display error messages, and Formulas can handle the validation logic. Pretty straightforward, if you ask me.
