How do i stop an IntValue from going negative?

I make money scripts a lot and I hate it when the intvalue goes negative, and i know theres a way to make it not go negative so, if anyone can help me out with this that would be great, thanks in advance?

Since you haven't provided any script, here are some options: When you deduct cash, check if that have enough, OR just have a while loop, that if the values goes below 0, set it back to 0.
