Something

I still want to be able to use !beer without getting an unknown beer command error. I also want it to let you give the Beer you stole to someone else with !beer Nick

So !beer would react the same as !beer drink 1 and !beer Nick would say I stole it and add a line where I give it to nick.

in my noobish way I tried changing the top line that had the unknown error to the previous beer line I was using before. THis obviously didn't work. LOL Can someone show me how to fix it to do what I want?

Code:
on *:TEXT:!Beer*:#: {
  if ($2 == $null) { $ent.default(beer,describe $chan gives $iif($2 ison $chan,$2,$nick) a beer, 4, 1800,msg $chan No more beer credit for you ; $+ [ ) ] , notice $nick cut it down on the beer :) }
  elseif ($2 == help) { notice $nick Beer commands: !Beer fill - !Beer drink <number> - !Beer add <number> - !Beer guess start - !Beer guess stop - !Beer guess score - !Beer stats }
