Scripts

Please help! I wrote the following script:

while GetObjectiveState('meet_demons', PLAYER_1) == OBJECTIVE_ACTIVE do
     sleep(5)
    end
    SetObjectiveState('hero_from_hell', OBJECTIVE_ACTIVE, PLAYER_1);
    MessageBox(GetMapDataPath()..'5.txt');

    while 1 do
	    if GetObjectiveState('kill_daeva', PLAYER_1)== OBJECTIVE_COMPLETED 
		and
		 GetObjectiveState('capture_mines', PLAYER_1) == OBJECTIVE_COMLETED 
		then 
    sleep(5)
		     SetObjectiveState('hero_from_hell',OBJECTIVE_COMPLETED, PLAYER_1)
		     SetObjectiveState('go_throw_dungeon',OBJECTIVE_ACTIVE, PLAYER_1)
     end
       end

After completing the "meet_demons" quest and closing the "5" message, the game freezes. What did I do wrong?
