Awesome mod but it seems to be missing the option to raise and lower the rack. Other options (light and base) work as intended.

Its not. You cant lower the top rack before the lower rack. So only the rack that can be moved has an active trigger. It has to be this way or else the animation would clip. And headers would go to the moon. So when you place it first time take note of the numbers. (If youre changing it to concrete pad)
Now on the control panel it will light green for which rack can be operated.
So place it, and check the control panel for the green light near its corresponding number, go to that trigger(stand on top of the number on the foundation) and activate.
