I'm trying to get a user to input a value between, say, -50 and +50. Is there an easy way to do this, or will I most likely be stuck to using an if sequence that displays an error message and rejects the number if it's outside that range? Then on the else part of it, I could have it enter correctly.
Is there an easier way to do this, by specifying the allowed parameters?
