Use echo to test your scripts.
on *:text:#*:#:{
echo -a : $level($fulladdress) <=9?
}
this helped alot mate, thanks
the screwup was on my side since on user list i thought
if i add ; infront of address that mirc ignores it then
only by removal it worked :P
thanks

@ctraltdel: thanks for effort too, but your snippet bans even if user is on lvl list :P
