My fault...

Code:
on *:text:!*:#yourchannel: {
  if ($ini(mycommands.ini,$1)) {
    describe $chan $replace($readini(mycommands.ini,n,$1,$rand(1,$ini(mycommands.ini,$1,0))),#2#,$2)
  }
}


And you can rename mycommands.ini to something more appropriate if you like. Just make sure to replace the filename in all locations of the script.
