    @timtower sorry i fixed that. it wasnt the problem. it still doesnt work :( sorry for wasting your time. it is getting caught on
    Code:
    try {
    
    
    if(args.length==2) {
    if(Integer.parseInt(args[1])>200) {
    sender.sendMessage(ChatColor.RED+"Use a hight under 200! (/parkour start 150)");
    return false;
    }else if(Integer.parseInt(args[1])>0&&Integer.parseInt(args[1])<200){
    Location teleport = new Location(player.getWorld(),player.getLocation().getX(), Double.parseDouble(args[1]), player.getLocation().getZ());
    Location block = new Location(player.getWorld(),player.getLocation().getX(), Double.parseDouble(args[1])-1, player.getLocation().getZ());
    Block tped = world.getBlockAt(block);
    tped.setType(Material.EMERALD);
    player.teleport(teleport);
    }
    }else {
    
    }
    }catch(Exception e){player.sendMessage(e.toString());}
    and im getting a errror about invalid integers. im going to try again tomorrow
