Hello,
I just found this thread cause I had the same problem as the thread starter.
This "cockpit argument in range" seems to be a problem in more than this first training mission. I tried the first campaign mission, the hangar just opens and nothing happens. After reading about this cockpit argument error I changed the first 2 occurences of this argument min value to 0 and now at least the first instructions are displayed. As i am a total noob regarding the dcs mission editor my question is:
Would it be a good idea to just change all of these min values to 0 (in all training and campaign miz files)? Maybe with some kind of script or little program. I looked in the mission file in the miz file and there a lot of these c_argument_in_range keywords. So it shouldn't be that hard.
regards
