Validating max number of characters in input field

The code I was executing doesn't work with an && but it works with a '.' in a TRUE case statement.

You have been shown with numerous examples and tl;dr's breaking down exactly what is really happening in that condition. So at this point, either a) you still don't understand, and I don't know how better to explain it to you, or b) you do understand, and for some reason that is unclear to me, that is in fact the intended behavior you want out of your script. In either case, I guess I have nothing more to say.
