Ehmm .. I'm not sure that I understand what you mean, but I think you need something like this:

Code:
on *:text:$100:#: {
  if (%pretext == how much) {
    set %tk $rand(1,2)
    if (%tk == 1) { set %pretext that is a lot. }
    if (%tk == 2) { set %pretext that is expensive. }
    msg $chan %pretext
  }
}


But this is not the best way to have your bot talking, you will end up with dozens of on text events. And what to do if somebody says: $200? Or $1000?
