I'm not one to say if that would even help. Maybe someone else can open it, but I can't.
You might be needing the "toggle" flag enabled on the func_door.
OK so it did work this time. You have a lot of problems with your map including using the carve tool and not even func_detailing what you carved (not that you should be using the carve for imprecise arches anyway) and you also have a leak.
But to fix this specific problem, you need to change your trigger_multiples' Delay Before Reset to 0, not -1. The func_door is fine as -1 because the trigger is activating it, but if you put the trigger to -1 too, it's essentially only going to activate it once (open but never close).
What do you mean by carve?
Then how do you make those bow shaped structures? And I just uploaded it on another website.
Forget I said carve tool. It's essentially just when you cut a brush with another brush, and it creates the shape you want but not at all optimized. Hopefully others that are better explaining these things will take a look at my screenshot and explain it better. I totally understand it, I'm just not good at explaining it - I'd make a terrible teacher.
The thing you really want to concentrate on is the leak.
BTW, how did you get the vmf to load the second time?

the arch tool isn't a bad place to start. also, they definitely need to be func_details, especially as they are now.
