Scripting Problem Help Please

[HoyChampoy]

Hey Guys. I have a complicating problem. I am making a custom story and right now there are two map files. I have a level door that sends you from room 1 to room 2. I was able to allow the player to go back from room 2 to room 1 just in case they forgot something. But, in room 1, there are script areas that the player encounters that sets off a scare. The problem is that when a player leaves room 1 but decides to go back from room 2, they happen to run into a script area that they previously ran into earlier, causing the same scare to happen again. Also a door (not the level door) they had to unlock in room 1 becomes locked again. Is there a way to disable the script areas after you enter them, even if you leave the map, come back into the map, and enter the script area? Help would be very appreciated!
