Laserdrome

Hey I'm relatively new to scripting, and I was wondering if there's a way to set horde modules to be activated by triggers I've placed, rather than using the parameters within the module itself. I did a google search and found some tips, but I keep getting errors. I want a few hordes to spawn at multiple locations on a street after a certain task is completed, so by the time the player exits the building zombies will be swarming the area.
