I have an error when i try to install this code.

// Returns the count of all the monsters on the specified map with the given monster id.
// mobcount2 <map>,<mob id>;
static int buildin_mobcount2_sub(struct block_list *bl,va_list ap)
{
	int class_=va_arg(ap,int);
	struct mob_data *md = ((struct mob_data *)bl);
	if(md->class_ == class_ && md->status.hp > 0)
		return 1;
	return 0;
}

BUILDIN_FUNC(mobcount2)
{
	const char *mapname;
	int class_,m;
	mapname=script_getstr(st,2);
	class_=script_getnum(st,3);

if(!mobdb_checkid(class_)) {
		script_pushint(st,-1);
		return 0;
	}
	if((m = map_mapname2mapid(mapname)) < 0) {
		script_pushint(st,-1);
		return 0;
	}
	if(map[m].flag.src4instance && map[m].instance_id == 0 && st->instance_id && (m = instance_mapid2imapid(m, st->instance_id)) < 0)
	{
		script_pushint(st,-1);
		return 0;
	}
	script_pushint(st,map_foreachinmap(buildin_mobcount2_sub,m,BL_MOB,class_));
	return 0;
}

 this is the error

 

script.c: In function ‘buildin_mobcount2_sub’:

script.c:4826: error: ‘struct mob_data’ has no member named ‘class_’

script.c: In function ‘buildin_mobcount2’:
