Problem with mission end marker

[Necramonium 10]

I have made a mission (Sniper Alley), it's very popular on Steam Workshop, was nr 1 for over a week! But there is one problem i can't seem to be able to fix seeing i am pretty new to all the scripts that come with arma 3.

The problem is in the the last objective where the players has to get to the extraction chopper, but for some reason that objective will not be marked as completed when the player has been extracted! How do i fix this? Someone already suggested the key method:

activateKey "mission_name_key";

in: description.ext:

doneKeys[]={"mission_name_key"};

But when i do this, the mission ends as soon as its started.:(

Please help me out with a clear answer seeing i barely know nothing about coding and scripting.

Do a trigger that checks when the player is in the helicopter, then activation would be your extraction task completed. I would add a sleep in there otherwise it will fire off as soon as he is in the helicopter.

Sync a trigger to your succeeded task:

cond: player in chopa

I have some ideas and updates for your mission, I will send you a PM later.
