try this:

on ^*:kick:#: {
  if (($nick == %nick1) && ($knick != %nick1)) { inc %knick1 }
  if (($nick == %nick2) && ($knick != %nick2)) { inc %knick2 }

If you use two of the same types of events, only ONE will work. Also, if you want it to trigger on more than two nicknames, you might want to use a variable, or a user level, or mirc's internal lists somehow or a hash table (some I know nothing about)

Those who fail history are doomed to repeat it
