Application Script wont work becuase I am recceving an Undefined Variable

[topflight]

Hello I am creating my registreation page and if the member select a certain group that will get an ID number plus 1 (i.e Group A = 1000 if a new member were to join it their ID would be 1001 and if another member join their id would be 1002.) Each group has their own A= 1000 B= 2000 C= 3000 4= 4000. But for some reason they are not going up. And I think the reason it is not working because I keep getting an undefined variable login on line 64,71,82 Here is my code:

 

 

64:

            $update = mysql_query("INSERT INTO `pilots` (login,pwd,fname,lname,email,hub,thours,thoursc,rating,vatsimid,date,ip,status,hm,ed,bm,active

 

71:

pending ID of ($login)

 

82:

Is an email with the login information

 

This is my code:

 

 

<?php
include 'db.php';
$error = '';
session_start();
if(isset($_SESSION['LOGGEDIN'])==TRUE){
echo'You are already a member ';}

if(isset($_POST['apply']))
