expression 3D controlls 2D

Hi everyone,

I would like to control a 2D property [pre-comp with various text layers] with an
Invigorators z-position.
The task is to z-pos. + z-rotate back the 3D Invigorator with its own set-controlls
and take the 2D text-precomp [sticking flat on the front side] with it.
All my expression attempts are not working. How would I write such a thing?

Thanks in advance. Cheers

Frank
