Multiboard Help

I would like to know how to make a multiboard (Or if its a leaderboard) That Has time and it works just like a really one with the seconds, also I'd like to know how to make a health and mana bar that when you use or get hit your health/mana go down.

The time thing is not a leaderboard or multiboard, it is a Timer that starts and a timer window.Like this:
Countdown Timer - Start YourTimer as a One-shot timer that will expire in 30.00 seconds
Countdown Timer - Create a timer window for YourTimer with title Your Title
Set YourTimerWindow = (Last created timer window)
Countdown Timer - Show YourTimerWindow for Player 1 (Red)
YourTimer is a timer variable, and YourTimerWindow is a timer window.
