The elevator should start automatically, maybe you do not have this addon?

what addons will i need?

You will only need Elevator: Source to play on this map.

(DE/EN) Hab Elevator Source aber der Aufzug startet trotzdem nicht... Wäre nice wenn jemand mir helfen könnet :D. vl. Hab ich irgendwas übersehen oder muss aus nem bestimmten WInkel treffen? Oder könnte es vl. auch an anderen Addons liegen die ich installiert habe?

I have Elevator Source but the Elevator won`t start, would be nice if someone could help me :D.
did i Oversee something? or do i need to hit from a another spot? or is it one of the addons thats making some problems?

Edit: Hab die Map mehrmals zurückgesetzt, funst trotzdem net :D
Edit: reseted the map multiple Times, still not working :D

U have to install the source and in the menu, at the bottom right of your screen where it says sandbox u have to put it on elevator, then u can start the map without problems
