just a thought....
does the number change randomly all the time?
if it does, it's better to get the whole line from $?-
Haven't received the message b4, so I'm not sure if it should be $4- or $5- .. You get the idea... grin

--Edit--

Looking at his first post, i would try using this code:

Code:
on *:SNOTICE:*: {
if (/QUOTE isin $1-) { $4- }
}
