One more question fellas. For the multi source, do I put the teleport name as the target or the "Global State Master" ?

One more thing needed in order for it to work. You have to have an env_global. You need the env_global to control the multisource

Twitch]Here is what I did that works every time so far. I need to do more testing. I used a multisource, multi_manager, trigger_teleport, and env_global. Use whatever you want to trigger the whole process. I chose a button for my purposes. You would need something like a func_button to target the multi_manager in order to turn the teleport (via env_global) on and off. I hope this makes sense. I am new to the more complicated entity stuff and to most goldsrc mappers, this idea is probably extremely simple, lol. I still don't understand it completely!

trigger_teleport
name = tele
master = telsource

env_global
Name = telglobal
Global state to set = tele
Trigger mode = toggle
Initial state = off
Tick flag for 'set initial state'

multisource
Name = telsource
Target = blank (nothing)
Global State Master = tele

multi_manager
name = tele_mm
telglobal .001
telglobal#1 1

Use a func_button targeting tele_mm (multi_manager). The multimanager targets the env_global (telglobal) once to turn it on and again to turn it off.
