Scripts

I recently downloaded a manual from the author: ogo. And I realized that the first thing he teaches is exactly what I need. But for some reason, the script doesn't work. I named the region the same way. I can't figure out what the problem is. I enter the region, and nothing is displayed...

Here is my script.

function kamillaF()
Trigger (REGION_AND_STOP_TRIGGER, "kamilla", nil );
MessageBox ("/Maps/SingleMissions/Island_Triads/text1.txt");
end;
