[Question] Countdown 2

[p1g 0wnz]

I know some here probably would say just edit your old post. But that's useless because people usually just think they already helped me. But anyway my new question is here..


1. Is there a way i could make my countdown beep once it reached 0?

2. How can i make it you can't do -1 (or any number) Because if they do that they go up instead of going down :/
