Thanks for checking it out. Frustratingly, it's working today. In fact I now cannot get it to not work. lol. :wallbash: The setup is straight forward. Place the door, open the properties, set the reference to the pull chain in the Activate Parents tab. Last night, if I swapped the door out for any other door, like NorPortcullis for instance, it would work. Change that back to the NorSecRmSmDoorSm01 and it would fail like in the video. I don't like when things magically work without me doing anything to fix it. I'm still learning the CK so I'm sure I did something wrong somewhere... Thanks again, Dave.
