Valve Hammer 3.5 How do i use "trigger_changelevel" properly? Thread

So i use "trigger_changelevel" but it does not work i am doing it wrong i now i am i know how to do it and its easy, but im scared my map will fail and will break i know how to do it now but im not sure if the youtube video i watched on it works because he did it on WON not Steam here's the link to the video and tell me if the "trigger_changelevel" system changed in steam.

LINK: Youtube.com

Thank you, Have a nice day!

As far as I can remember, there was no difference between the won and steam version of hl.

Here is an example rmf with different level change versions (with and without the option to go back and forth)
