Alright, I got everything working thanks to all of your advice! Followed it to the letter. I now have a lovely rendition of the Detroit Stove Works c. 1883, full of crushers, steam engines, grinders, molten metal, platforming and assassins from hell...such nasty hazards they all are! One thing eludes me...creating a locked door. It appears the "LOCKED" flag is missing from Func_Door! A locked door that you must find a key to is a pertinent thing in my storyline.
