When I download maps from other people, where do I put them? In the packages folder? I tried that and when I opened PAS, no new maps appeared. What do I do?

Scenario: I put a switch on the map and set it's trigger type to 10 and it's trigger tag to 1. Then I put a door on the map and set it's trigger tag to 1 also. I go down to edit mode and walk up to the switch. THe switch moves, but the door does not open. How can I make switches open doors?

I've got door trouble. On my PC, both premade and the doors I make don't run. Premade eans the doors on the maps built in to the game. I have a laptop running the same version as the PC, and there is no trouble at all there. Any ideas as to why this may be happening?
