you can chage things like this

on 1:TEXT:!future:#: {
  if (%future == on) {
    halt
  }
  else {
    if (future !== on) {
      set %future on
      msg $chan Well well, hello there, $nick $+ . Would you like for me to tell your future??
      timer 1 2 msg $chan !Yes or !No.
      set %choice on
    }
  }
}

into this

on 1:TEXT:!future:#: {
  if (!%future) {
    set %future on
    msg $chan Well well, hello there, $nick $+ . Would you like for me to tell your future??
    .timer.future 1 2 msg $chan !Yes or !No.
    set %choice on
  }
}

instead of seting the vars to off just unset them
also you sould name ur timers
