I need help with linedef executer #15

[Blue Fox2]

I'm trying to get it to open a door when the enemies in the room are gone, but I can't figure this out. Can somebody help me?

Linedef executors are a little more complicated than other map effects. The Wiki article has some information on how to use them, but it's a little sparse. It's worth reading, though. Once you've worked out how to use linedef executors in general, you should be able to figure out the 'no enemies' one.

There is no wiki article about it. It's in red... Can somebody give me an example?
