Ladder Area Problem

[DRedshot]

I've got a ladder area in my map, but it doesn't work at all. It's about 20cm away from the ladder entity, but it just wont work. It only works when i move it about a metre away. The only things the Ladder area is in contact with is two script-areas and a fogbox. I dont want the ladder area to be a metre away from the ladder, so could anyone suggest any solutions?

Thanks!
