Activate a trigger when going trough another one

[ziberty]

Hello,
I'm making a map where I need to activate a trigger when going trough another one. I don't know if that's possible, but I'm almost sure I saw that on nadeo'ica and on other RPG maps... I've been messing around the mediatracker for some hours and I don't know how to do that.

When you're setting the trigger point you can give conditions. I circled it red for you here:


(I'm guessing it's called "Condition" as it's the most fitting translation for the german "Bedingung" )
