Okay you may have to go back a bit to an earlier save so that you can, 1.pull the lever to stop, the crain above where you can get to it on the upper level, put batteries into the doll, hang the doll. 2. then go down hide near box and then pull switch when Flemm comes in. This is the order I did it and it worked. Hope this works for you.

PS if you get this to work be sure and go out the door you came in and don't do a travel or you won't get to move on.
