oh it seems like there's nothing i can do to unban my address on that channel coz' i'm not a op on that channel, im just a chatter. :(
well tnx anyway.

You cannot get unbanned from a channel you have been banned from, unless it is your channel or you are some sort of administrator on that channel. In the case that you are an administrator, /chanserv unban #ChannelName me.

hi, I need help, they ban my address on my favorite channel on DALnet I don't know why so now I can't join the channel please help me, can you give me a code to unban my address. And one thing that I really don't know is to where should I type or paste the code should I type it on the scripts editor? I really don't know where please I need help.

I would just like to point out that the parser will run your if-then-else statements much quicker if you group your comparisons with more brackets, ie:

if ((this) || (that)) { DO }

is quicker than:

if (this || that) { DO }

You don't need your 'halt' statements. In fact, since you are '/whoising' people, you may want to use 'haltdef' to halt the response the IRC server gives you, since you don't want your window flooded every time you '/whois' for a mask.

Here is an 'example' rework that you may use if you want:

on *:Text:!unban *:#:{
  if (($nick isop $chan) || ($nick ishop $chan)) { .enable #banunban | who $2 | set %ban_var $chan -b $2 }
  else { .notice $nick Sorry, you need to be at least halfop to use this command. }
}
on *:Text:!ban *:#:{
  if (($nick ishop $chan || $nick isop $chan)) { .enable #banunban | who $2 | set %ban_var $chan +b $2 }
  else { .notice $nick Sorry, you need to be at least halfop to use this command. }
}

#banunban off
raw 315:*:.disable #banunban | .mode $gettok(%ban_var,1,32) $gettok(%ban_var,2,32) $address($gettok(%ban_var,3,32),2) | haltdef
raw 352:*:haltdef
#banunban end

yeah now i see you've updated.

the problem was that unset variables.
now looks nice

nice code :)

i try. but dont know why, dont works with me
