while 1 do
  pfonix = GetHeroCreatures( "Main_Hero", CREATURE_PHOENIX);
  if pfonix >= 5 then
    SetObjectiveState("dzad3", OBJECTIVE_COMPLETED);
    SetObjectiveState("dzad2", OBJECTIVE_FAILED);
    break;
  end;
  sleep(1)
end

The last loop is missing a sleep command, so if the condition pfonix >= 5 (correctly spelled phoenix, not pfonix in English) is not met, the game will crash after the first iteration. Something like that.
