Trying to fix Exploit in buff script

[Huppy]

This buff bot script works perfect except for one little glitch.
Normally it won't cast the gallantry on any toon lower than 61.
As long as the toon that hails the npc is 61+, it will cast either
single or group buff. BUT, if that same 61+ toon lets a lower
level toon in the group, that lower toon will also get the gallantry.
Is there a way the script can check all the toons in the group,
to see that they are all 61+, before casting the gallantry ?
Even if the npc doesn't cast at all with the lower toon in group.

sub EVENT_SAY {
if(($text=~/hail/i)&&($ulevel<=60)){
quest::say("Sorry $name, your level is too low for my buffs.");
}
elsif(($text=~/hail/i)&&($ulevel=>61)){
my $Group = $client->GetGroup();
if($Group) {
$Group->CastGroupSpell($npc, 18323)
}
else {
my $GetPlayerID = $client->GetID();
quest::selfcast(1824;
}
quest::say("Incoming Gallantry for $name");
}
}
