There is no $chan in a raw event, try $1 instead.
No such command as /closemsg. Try window -c $nick.
Again, I do not suggest while loops in text commands.
Are you certain the ignore command is being called? Do you see their nick in the ignore list?
/echo -a is a scripters friend. We use echo to show us exactly what is going on in a script. You can use it simply let you know that a comparison checked true or to return the actual data in the event.
raw whisper:*:{
echo -s WHISPER $1-
}
This here alone will tell you a lot about the whisper event.
You can also use $rawmsg to get the actual data the server sends you.
