DDR Getreidelager placeable v1.0.0.1

I once thought that to do I do placable the Prefab version of DDR grain storage.
I am still very new and this is my first attempt at a Prefab ever make placeable.
It works to open the door. Light switch If interior lighting and the on and off the ventilation can be activated also.
The log is with me after much back and forth also doktor'n errors.
A thank you from you would be really great and lifts the spirit to also move on.
