"You must first activate a bot for the channel." How do I activate a bot for the channel? anyone? pls

I pasted this into the remote in script editor

on !1:JOIN:#roomname:.timer 1 1 $iif($nick !isop $chan,.notice $nick Welcome to $chan please state your age like this: !19 $+ $chr(44) if you do not state your age you will be kicked.)
on $*:text:/^!(\d+)/S:#dirty: {
tokenize 32 $strip($regml(1))
if ($1 >= 18) && ($1 <= 50) mode $chan +v $nick
if ($1 < 18) { mode $chan +b $wildsite
kick $chan $nick Come Back After Your 18th Birthday.}
}
why doesn't it work?
