I'm going to attempt this one myself, can you tell me if it's good? I need the halt command written in like that as a part of the bar code, not to halt the /write script. I dunno if I did it properly.
on addbar:TEXT:!addbar *:#: {
write C:\IcyBot\Scripts\callup_banners.mrc if ($strip($$1) == $+ $$2 $+) { msg $chan $$3 | halt }
notice $nick Bar added.
}
