Add  session start      at the beginning of your page before any HTML  You will have something like     lt  php session start    include  inc incfiles header inc php    gt   lt html gt   lt head gt   lt meta http-equiv  Content-Type  conte      Don t forget to remove the space you have before

First  you ll need to add session start   at the top of any page that you wish to use SESSION variables on   Also  you should check to make sure the variable is set first before using it   if isset   SESSION  SESS fname          echo   SESSION  SESS fname        Or  simply   echo  isset   SESSION  SESS fname        SESSION  SESS fname      Visitor
