I went back and edited chapter 4---to make it readable ---but the orginal chapter 3 had already been deleted from the system ----and I really do not have the time to edit each authors margins---you margins are set correctly but if you will notice there is a little arrow in the rule ---it must be set the same as your margin or it will allow you to over run your margin ---this little arrow is a stop---and that must be set no farther than the start of the darkened portion of your margin in the ruler
