I'm not exactly shure how to do it, but I would like a script that when that when anyone on the Channel types for e.g. "Have you Seen (Nick here)" it replies " I havent Seen (Nick Here)"

How would I do that?
Should I use " on 1:text:Have you Seen $nick:#:/msg $chan I havent Seen $nick"

It does not seem to work

Thanks!
