Notice: Undefined variable: error_msg in D:\data\Inetpub\wwwweb_verynew\mobile_form\plan.php on line 15

15: if ($error_msg){
16: $_SESSION['error_prn']=$error_msg;
17: header("Location: page1.php");
18: }

Here is where the error_msg is set:
if ($_POST['email'] === $_POST['vemail']){ //AND check_email($_POST['email'])){
$_SESSION['email']=$_POST['email'];
} else {
$error_msg .= "E-mail addresses don't match";      
}

Any thoughts?

>>Here is where the error_msg is set:...
but that must appear before line 15 on the SAME php file. Also, if you are using dot equal
$error_msg .= "E-mail addresses don't match";  

then $error_msg should be initialized to "". You could even try changing line 15 to:
if ( !empty($error_msg) ){

I would think that when the page is first launched $error_msg is not defined, nor set.
You might try something like:

$error_msg='';
....
if ($_POST['email'] === $_POST['vemail']){ //AND check_email($_POST['email'])){
$_SESSION['email']=$_POST['email'];
} else {
$error_msg .= "E-mail addresses don't match";      
};
...

15: if ($error_msg <> '' ){
16: $_SESSION['error_prn']=$error_msg;
17: header("Location: page1.php");
18: }

I'm sorry, this is the 2nd page, in a multi-page form, and the error msg is set after validation, see below entire code.

<?php
session_start();

if ($_POST['email'] === $_POST['vemail']){ //AND check_email($_POST['email'])){
      $_SESSION['email']=$_POST['email'];
} else {
      $error_msg .= "E-mail addresses don't match";      
}
$_SESSION ['name'] = $_POST ['name'];
$_SESSION ['mobile_num'] = $_POST ['mobile_num'];
$_SESSION ['password'] = $_POST ['password'];
$_SESSION ['country'] = $_POST ['country'];

//Validation Ended
if ($error_msg){
      $_SESSION['error_prn']=$error_msg;
      header("Location: page1.php");
}

//function check_email($addr){
//      return preg_match(".+@.+.[\d\D]+",$addr);
//}
//$_SESSION = $_POST;
?>

Like I said before, initialize the variable
<?php
session_start();
$error_msg="";
if ($_POST['email'] === $_POST['vemail']){ //AND check_email($_POST['email'])){
      $_SESSION['email']=$_POST['email'];
} else {
      $error_msg .= "E-mail addresses don't match";      
}
$_SESSION ['name'] = $_POST ['name'];
$_SESSION ['mobile_num'] = $_POST ['mobile_num'];
$_SESSION ['password'] = $_POST ['password'];
$_SESSION ['country'] = $_POST ['country'];
 
//Validation Ended
if ( !empty($error_msg) ){
      $_SESSION['error_prn']=$error_msg;
      header("Location: page1.php");
}
 
//function check_email($addr){
//      return preg_match(".+@.+.[\d\D]+",$addr);
//}
//$_SESSION = $_POST;
?>
