this is what i got:

on ^*:text:xdcc send #*:?: {
/msg $nick You must use /ctcp $me $1- to download from this bot.
}

as you can tell, its for xdcc and what i want is if someone messages my bot with xdcc send, they do it in the format of xdcc send #2 and it reply's You must use /ctcp <botnick> xdcc send #2 to download from this bot. what i want is to make it so directly after the # MUST be a number for the bot to reply with the message, so it reply's if someone msg's it with xdcc send #2, but not xdcc send #onsgonfhij(any random letters/numbers).
