Session Variable in PHP Issue Occurs - php

Question

In my page, I have:
1. Registration Page
2. Login Page
3. Successful Registration Page
4. Referral Form
In my registration Page, User can register thru this.
In my Log-in page, I have two types of user, Applicant and Employee
In my Successful Registration Page, there will be a button there going to Referral Form.
In my Referral Form Page, I have a modal there to update referral information provided by the user during the registration.
The following information are:
Referrer ID
Fullname
Current Position
ContactID
Email Address
MObile Number
Member Since
If you created an account on my page, either you are a Applicant or Employee, if you successfully register, my successful registration page will prompt to you and once you have click the button going to Referral Form The following information will be displayed to your referral information based on you supplied during the registration.
If you register as an Applicant, your Referrer ID is always set into 0 and you may edit it thru Referral Form Page
or if you register as an Employee, your Referrer ID is based on you provide during the registration._
Example:
Referrer ID (Allowed to edit if you register as an applicant)
Fullname Sherlock Holmes
Current Position (This has no value and may be edit once you created an account)
ContactID CON12344
Email Address SherlockHolmes#gmail.com
MObile Number [phone]

Here's my problem that I encounter.
I created an account and Successful registration page prompt to me, and I click the button going to Referral Form Page to edit my information. I edit it and Log-it out and try to relog-in, My Information updated and now reflecting on my Information. It works well.
But
When I created an account and promt successful registration page and click the button going to referral form page, If I did not edited my information and tried to log it out and try to re-login, my information becomes having all null values. LIke this,
Referrer ID 0
Fullname
Current Position
ContactID
Email Address
MObile Number
Member Since
Which was incorrect because even I did not edit my information, my information should just becomes like this.
Referrer ID 0(You can edit it)
Fullname Sherlock Holmes
Current Position (You can edit it)
ContactID CON12345678
Email Address sherlockholmes#gmail.com (You can edit it)
MObile Number [phone] (You can edit it)

Problem Occurs when I didn't edit my information for a new created account, but when I edit it before I log it out, it's okay.
here is my Successful registration PHp
<?php
include('../include/dbconnection.php');
include('../include/functions.php');
if(!isset($_SESSION))
{
session_start();
}
$empid = $_SESSION['SESS_EMP_ID'];
$conid = $_SESSION['SESS_CONID'];
$fName = $_SESSION['SESS_FIRSTNAME'];
$lName = $_SESSION['SESS_LASTNAME'];
$contactNo = $_SESSION['SESS_CONTACT_NO'];
$mobile = $_SESSION['SESS_MOBILE'];
$email = $_SESSION['SESS_EMAIL'];
$bday = $_SESSION['SESS_BDAY'];
if($conid == '')
{
echo ("<SCRIPT LANGUAGE='JavaScript'>

}
else
{
//Nothing

Here is my code in Referral Form

session_start();

Do I have problem passing the session variable when the user didn;t fill up the information after they created an account?
If user edit and fill up all information and try to relogout and relogin. It seems okay and works.
But after user created an account, and If he didn;t edit the information and log it out and try to relogin, it does not reflect the values. Can you help me with this
