Trouble With Teleporters

I’ve looked up many tutorials on making teleporters and they seem so easy to make and yet when I put them in a map, they don’t work.

Video of the problem:

I’ve made a brush, made it trigger_teleport. Then I put the info_teleporter_destination entity somewhere else. Yet, when I walk into the trigger, NOTHING HAPPENS. I’ve managed to make a platform move between points using func_tanktrain, path_track, and trigger_once, which seems significantly more complicated than this. WHY WON’T IT WORK?! It is driving me up the fucking wall. I won’t be able to sleep until I resolve this.

Have you set up Always active in the flags?

Solved. You have to check “clients” under flags.
