Problems with a signal script

[Neiv]

I have a script that is supposed to call the guards to come in and kill the non-allied player who hails the king. On my king NPCs I have the following script:

elsif($faction >= 2)
{
quest::signal(999139,5);
quest::signal(999140,5);
quest::say("Why should I suffer the likes of you? You shall pay for your presumptuousness.");
quest::shout("GUARDS!");
}

On two of the kingdom guards I have this:

sub EVENT_SIGNAL
{
quest::attack($name);
quest::shout("The King calls for help!");
}

The shouts work fine in each case, but the guards do not come. I tried changing $name to $client, with the same results. Then I changed $name to the PC's actual name (Neiv), and it worked. Obviously I do not want to hard-code my player name in the quest script. Why isn't $name working? How do I adjust the script to recognize any player who hails the king?
