Welded Groups Unscriptable?!

I’m attempting to script a welded piece (worth 12 objects) to go travel up or down, like an elevator. Here’s what I have so far:

OBJECT
Interactive: Switch (1x1x2; Keypad)
SCRIPT 1
When…
Condition: Interacted
Do…
Action 1: Power: Set
Channel: alpha
State: Toggle
Transfer: ACTIVATOR

OBJECT
Floor (24x24x4)
SCRIPT 1
When…
Condition: Power: Check
Channel: alpha
State: On
Do…
Action 1: Move: Offset
Z / Vertical: 15.00
Local: On
Time: 2.50
SCRIPT 2
When…
Condition: Power: Check
Channel: alpha
State: Off
Do…
Action 1: Position/Rotation: Reset
Time: 2.50

Obviously, I’m doing something wrong, but I don’t know what. Feedback is appreciated!
