What do you want the countdown timer for???
Here is an easy trigger example.. (This is assuming you have the map set up to play)

Condition:
- Elapsed time is at most 10 game seconds
Action:
- Modify Countdown timer Set to 20 Game Seconds
- Set 'Switch 1'

Condition:
- 'Switch 1' is Set
- Countdown timer is exactly 0 Game Seconds
Action:
- Modify Countdown timer Set to 3 Game Seconds
- Preserve Trigger

That switch is just so the second trigger doesnt go off before the timer is ever there..
Any other questions about CountDown Timers ill check forums.
