Hello.
The detection trigger needs not to be atached to the sub.
For creating the Dynamic Group you have to put the ships where you want them to appear, with their respective waypoints, etc.
Then you create the group, include all the ships in it.
In the probability box you have to set 0, because if not, the gruop will appear at the end of the mission.
Finally, in the detection trigger, on the last page, you have to set "create dynamic group" and select the group.
Another thing, if you are planning to make goals or triggers for that group, you have to include them in the group itself. i.e: you make a D group with 3 ships and a destination triger, the total objets you have to set are 4 (the ships and the trigger).
Hope this helps.
