I'll accuse you of being a dimwit. The questions you ask do not show you trying. The code that _is_ posted is not straightforward or geared towards readability.

If you really want to do that, then why do you insist on one-liners? Write out the logic with a sequence of if statements. That is easy to understand, gives clearer error messages. The solution by Nobody is fairly foolproof, and the logic is clear. What's not to like?
