If you did this in your server config, Saves time, when your staff get their O-Lines points it to your Staff channel, just a thought.

....

Instead of using

on *:TEXT:!staffme:#: {
  if ($nick isop $chan) {

You can set the channel to a variable and make it to only pick up on the command IN that channel. Let me break down my code for you.

;When you load the script it will run this..
on *:load: {
;setting the channel set for the staff only
 set %StaffChan $$?="What is the staff channel?"
;setting the channel the StaffChan is set to look for ops in
 set %UserChan $$?="What is the user channel?"
}
;This uses %UserChan because that would be the channel you want the ops to be able to ;get access to your staffchan
on *:text:!StaffMe:%UserChan: {
;checking if the user has op in %UserChan, if they do it will invite them to %StaffChan
 if ($nick isop #) { invite $nick %StaffChan | notice $nick Invite sent. }
;But if they aren't
  else {
   notice $nick Denied. You aren't op in %UserChan $+ .
   msg %StaffChan $nick tried to get in.
;It will deny them, and notify %StaffChan that they tried to get in.
  }
}

I left out the channel name so you could make it yourself.. As Korvin said, it is an obvious change that you would do.

What would you do if someone who was op in another channel you were in typed the command to gain access to the staff channel that was for the staff of your user channel?

on *:TEXT:!staffme:#: {
  if ($nick isop $chan) {
    invite $nick #insertstaffchanhere
    notice $nick Invite sent.
  }
  else {
    msg $chan Sorry, you dont meet the criteria, $nick
    notice $nick No staff, no invite ..
  }
}

Your code is functional, but only to a degree.

Try...

on *:load: {
 set %StaffChan $$?="What is the staff channel?"
 set %UserChan $$?="What is the user channel?"
}
on *:text:!StaffMe:%UserChan: {
 if ($nick isop #) { invite $nick %StaffChan | notice $nick Invite sent. }
  else {
   notice $nick Denied. You aren't op in %UserChan $+ .
   msg %StaffChan $nick tried to get in.
  }
}

atr, thats an obvious adjustment that everyone and anyone would make -.-

Atr: You can set it up so it only works on the channel that its on, so that it only works for the ops #123.

Nice idea to it, you might need to add something in case it's used by an op on another channel, and then you're screwed xD
But other than that, not a bad first script.

 on *:TEXT:!staffme:#: {
  if ($nick isop $chan) {
    invite $nick #insertstaffchanhere
    notice $nick Invite sent.
  }
  else {
    msg $chan Sorry, you dont meet the criteria, $nick
    notice $nick No staff, no invite ..
  }
} 

<-- wtf ??? Fail I'd say wtf i mean C'mon

the code you have should work fine.

EMMURE thats weird, it didn't give me problems when I ran it :/

Script updated

This is how I'd do it.

on *:TEXT:!staffme:#: {
  if ($nick isop #) {
    invite $v1 #insertstaffchanhere
    notice $v1 Invite sent.
    halt
  }
  msg # Sorry, you dont meet the criteria, $nick
  notice $nick No staff, no invite ..
}

oh sorry, took me so long to write that last comment that you posted yours before me, so mine wasn't any use :P

yea, thats how youre supposed to do it. brad, that doesnt matter. he just forgot the closing bracket, he had the internal brackets just fine cept that extra he put after the first if.

Nope

on *:TEXT:!staffme:#: {
  if (something) {
    bleh
  }
  else {
    bleh
  }
}

no, put it at the very end lol

Yeah pretty new. Did I fix it correctly?

you forgot closing bracket

on *:text:*:#{
bleh
}
