U missed a parenthesis cold...

Code:
#showraws off
raw *:*:window -k0 @raw | aline @raw $numeric :  $2-  | halt
#showraws end
alias /showraws {
   if [color:red]([/color]$group(showraws)) { .disable #showraws }
  else { .enable #showraws }
}

But what's wrong with just typin /debug @d and looking for the numer >:D
