Need help about mvp rank statue

[Akbare-2nd]

I get an error when installing this script

Can anyone help?

I think the problem in here

OnNPCKillEvent: // Logic to detect when a MvP is killed
	if (getmonsterinfo(killedrid, MOB_MVPEXP) > 0) {
		.@selectIfKillExistQuery$ = "SELECT char_id, mob_id, kills FROM mvpladder WHERE char_id = '" + getcharid(0) + "' AND mob_id = '" + killedrid + "';";
		if (query_sql(.@selectIfKillExistQuery$) > 0) { // Exist a kill of that MVP so +1 to kill count
			.@updateLadderQuery$ = "UPDATE mvpladder SET kills = kills + 1 WHERE char_id = '" + getcharid(0) + "' AND mob_id = '" + killedrid + "'";
		} else { // Create a new kill of specific MVP
			//.@updateLadderQuery$ = "INSERT INTO mvpladder (char_id, mob_id, kills) VALUES ('" + getcharid(0) + "','" + killedrid + "','1');";
			.@updateLadderQuery$ = "INSERT INTO mvpladder (`char_id` , `mob_id` , `kills`) VALUES ('" + getcharid(0) + "','" + killedrid + "','1');";
		}
		query_sql(.@updateLadderQuery$);
	}
	end;
}
