spell scribe limiter

[Maceblade]

Was curious as to how I would go about limiting the spell scriber to not scribe rank 2 or 3 spells... if that part isnt possible how about just restricting the scribes to lvl 70 and below?

#NPC: Spell_Scribe (Tomes and Quests NPC)

sub EVENT_SAY

my $tomes = quest::saylink("Tomes");
my $spells = quest::saylink("Spells");
my $learn = quest::saylink("learn");
my $knowing = quest::saylink("knowing");


  if($text=~/Hail/i)
    {
      plugin::Whisper("Hi there $name, I am Galmoran, keeper of [$tomes] and [$spells]. How can I help you today?");
    }
    elsif($text=~/tomes/i)
      {
        plugin::Whisper("Yes, I know all the Tomes in the land. Just let me know if you wish to [$learn] them as well.");
      }
    elsif($text=~/spells/i)
      {
        plugin::Whisper("Spells, So many in the land. Would you be interesting in [$knowing] a few?");
      }
        elsif($text=~/learn/i)
          {
            quest::traindiscs($ulevel);
          }
        elsif($text=~/knowing/i)
          {
            quest::scribespells($ulevel);
          }
}
