Help with Forge on Halo 3?

[swoop86544]

On forge on Halo 3, how can I time particular items to appear and disappear? For example, I have an elimination chamber type map on foundry. I want one door to open and have the other doors open 20 seconds after the last one opened. I have respawn points. There are only six of them, and they're inside the cells. How do I make the players respawn in those areas and those areas only??
