Help with Countdown timers

Hi Kirupa Forum Community,
I am a new user who has been searching high and low on how to do a very specific countdown timer effect in Flash. I am a graphic designer that has minimal Flash experience although I can get simple things done.

I’ve done the countdown to a date tutorial successfully but that is not what I need.

What I want to do is have a countdown timer start at 10 min and when it is finished it would go to a next scene that would countdown from say 2 min and when that is finished it would go to the next scene and so on…

I also want a timer that would count down the total of all the scenes. So if that was a total of 20 min then it would count down from 20 to zero.

Each scene would have the total countdown and the scene countdown.

Maybe scenes are not the way to go? I don’t know what the best method is due to my lack of experience.

If anyone could point me in the direction of a tutorial or has a solution to this I would be greatly appreciative.

I’ve searched the forum but so far have not found my answer.

Thanks a lot in advance.

Joe
