well you just need to read the script, if you did get it on how it works you should be able to edit the script though
#####setarray .region_maps$[0],"prt_gld", "pay_gld", "gef_fild13", "alde_gld", "aru_gld", "sch_gld", "prontera";######
I`m not really using the script though that's why all I can give to you is the tip...
Read the script slowly and make sure you know where and when you will move to the next, etc...

well you see you kept missing some of the characters such as " : "
try it again after putting colon on those tags

if you can see this in the script

if(getmapusers("quiz_01") == 1) goto L_Champ; if(getmapusers("quiz_01") == 0) goto L_None; ... ... ... ... ... L_Champ: mapannounce "quiz_01","Mr. Dice: Come to me and tell me your name.",0; hideoffnpc "Dice#evnt1"; end; L_None: //disablenpc "Dice#evnt1"; hideonnpc "Dice#evnt1"; end;
just change it to:

if(getmapusers("quiz_01") == 1) goto L_LACK; //<----CHANGE THIS ONE if(getmapusers("quiz_01") == 0) goto L_None; ... ... ... ... ... L_Champ: mapannounce "quiz_01","Mr. Dice: Come to me and tell me your name.",0; hideoffnpc "Dice#evnt1"; end; L_None: disablenpc "Dice#evnt1"; hideonnpc "Dice#evnt1"; end; L_LACK: //<--------ADDING THIS SCRIPT announce "quiz_01","Mr. Dice: Event cancelled due to lack of participants.",0; disablenpc "Dice#evnt1"; hideonnpc "Dice#evnt1";

try this.. remove the "oninit:" add ,"All" after the map
from:
killmonster "bat_a02";
to:
killmonster "bat_a02","All";
