bedges, i've opened your example mision that you've attached to one of your posts here. i tried to edit a trigger (in editor), without changing anything, and when i click on OK, it says: unknown operator "setdamage".
if i try to enter the game, and use radio to destroy shilka, an error occurs in upper left part of the screen.
edit: setdaMMage works, tnx Ben.
another objection: when i put
1 setradiomsg "null"
i still have "Alpha" on the radio menu. i've tried this even with copying the mission in sigle missions folder, but its the same.
