Basic trigger question, From a frustrated newbie Options

[Niarbyl]

Hello all,

I'm new to MUD clients and I'm having trouble setting a trigger. What I want to do is to kill a mob without having to input the it's name so, on advice from other MUD users, I've set;

$1 tells the group whack $2 ($ being the world's variable command)
reply:
kill $2

but all I get is a message telling me 'There is no one here called $2'. I've tried it with various changes (for example % and %% in the reply) but, after hours of testing, I still can't get it to work

Can anyone tell me what I am doing wrong?

Many thanks
