How do I make a timer?

[undeadorcjerk]

I made a game that is timed, but the timer doesn't work. The people said that the game would be better with a timer, to tell how long they have left to play. I just can't get the timer to work. Plz help me, it is hard :banghead: .

This map has what you need, replace the 30.00 with how many seconds you want your game to last.
