Code:
  
on *:text:!dns:#mychannel:{ 
  if ($2 == $null) { /msg #mychannel Invalid query, no addresses being resolved | halt }
  else { /dns $2 }
}


in case someone types !dns, bot tells back "Invalid query, no addresses being resolved" so case 1 works, but case 2 never works...

even if i define: if ($2 != $null) { /dns $2 }
it wont work smirk

anyone can explain why?
