Uhm... stuck again...

Greetings!
Still in MandMandM  - this time i am now in room 16323 - Jack can't hurdle the facade that is in the way (the lever only lowers the right folding door, too).
The room below it (16123) is no help either - dead end.  
Advice cheerfully accepted,
Thank you,
DLC

Okay, I got out of room 16123 - found the secret hop-up and claimed my key that takes me to the right, then up to room 16324 and then LEFT to rm. 16323.
Now, I am in that room 16324, and Jack can't make it all the way up the ladder on the right..
what am I missing?
Many thanks,
DLC
