MW elevator / lift script and sounds pack

I set the Scripts of the Elevator in 2 Prims as logical. 1 Botton and 1 Platform. The Script is easy to edit and i set the Height to 5 Meters for a Test.

But when i stand on the Platform it moves without me! It works like a Phantom Prim. I wrote to the Creator, but i did not get any Answer until now. So i spend 200 L$ and cannot use it. That is a No Go and gets 1 Star instead of Zero.
