Make a script work only in 1 map

[eKoh]

Hello guys, I've just made one script that warps you once you get to Job lvl 10, but it is working on all of my maps.

 

I think it can be fixed with a map_flag, but I dont know how to create one by my own. I would really appreciate any help.

 

poring_gnd,0,0,0    script    OnPCJobLvUpEvent    -1,{
OnPCJobLvUpEvent:
if (JobLevel>=10){
    mes "[^001D9CGet Started^000000]";
    mes "It seems that you are ready!";
    next;
        mes "[^001D9CGet Started^000000]";
        mes "I'll take you to your next trip!";
        next;
            savepoint "prontera",155,179;
            warp "prontera",155,70;    
            }
}
