Eventscript not trigger a new event

[Morten L]

Hi, i have two setpoints that can be changed locally.
When one change, i want to update the other to be the same.

Im trying to do this with just two event scripts updating each other, but ofc it goes into loop.
But im certain ive read about a way to have a script not trigger a new event.
Am i right, or am i misremembering and have to use an intermediary value ?
