Thanks, but I dont want to mess anything up with my poor knowledge about scripting

. I just want to make maps

.
I would have assumed that it was a property or at least inside the scripts already attached to the trap. Like that CasterLevel, that is -1 atm. Changing that did nothing.
I just thought I missed something obvious. I will just state in the description its there and you can easily remove it. My initial though was placing a trapwire and if someone crossed a bell would ring. No bells in the enigine and while I could just place an area trigger to trigger a sound, I wanted the players to have a chance to find it and disarm it. That I did not figure out how to do.
Anyhow, it was just a thought and is not a necessity for the map. I already used way to much time on this map

(but still learning stuff and getting faster every time ;)).
