ELEVATOR GAME

When I open the cupboard to reveal the game, nothing works. I can't get the cursor to change, and the lever and the weight don't move. Have I missed something? I've been following the walkthrough very thoroughly, as this is my fourth attempt at the game, but still misssome moves

I've no answer on the technical difficulties, but you can skip the puzzle if you want, and just access the area from the trapdoor in the kitchen.

ty. i did that and worked the game out in the corridor.
