Forums Scripts & Popups replacing script needs revision

Hi, im using this script for a long time, but on the latest version(s) of mIRC it doesn't work well anymore:


on *:INPUT:*: {
IF ($left($1,1) != /) {
msg $active $replace($1-,brb,Be Right Back,lol,Laughing Out Loud,jk,Just Kidding)
HALT
}
}

The problem is that the command filter on the beginning gives a faillure. Also i want to add 2 more options to this script:
1. Is it possible to add a ctcp action to another client when a replacing of words has taken place?
2. Is it possible to use an external .txt or .ini file where the replacing words are stored (trigger word v.s. replacing word)?
