Forums Developers Where have I gone wrong?

I'm trying to change the default Nickname Bracket's in mIRC, but its not letting me. Here's the script I am using:

on ^*:TEXT:*:#:{
if ($nick isop $chan) { echo -mti2 $chan 15(@ $+ $nick $+ 15) $1- | halt }
elseif ($nick isvoice $chan) && ($nick !isop $chan) { echo -mti2 $chan 15(+ $+ $nick $+ 15) $1- | halt }
elseif ($nick == $me) { echo -mti2 $chan 15( $+ $me $+ 15) $1- | halt }
else { echo -mti2 $chan 15( $+ $nick $+ 15) $1- | halt }
}
on ^*:TEXT:*:?:{ echo -mti2 $nick 15( $+ $nick $+ 15) $1- | halt }

Here's an example of what happens:

* Friend join #channel.
(Friend) Hey Man
(Friend) Whats up?
<Me> Nothing Much Man, Yourself?
(Friend) Not Alot.

Can you see what I mean? The brackets aren't changing for myself, but they work on everyone else.

To me, it looks fine... dunno what you guys think of it.

Where have I gone wrong?

Also, whats the "thing" for nickchange, like up there its on^*:TEXT blah blah blah, whats the one for nickname changes?
