Problems redirecting to next pages

I have recently tried this coding to update to my database it works differently in two browsers IE and Chrome. In chrome it just goes to the next page (before it was adding data to DB) and not going to next page. Now IE just adds data to DB and does not go to next page. Can someone take a look and let me know what I have to do to fix this. thanks

<?php

  @include('Connections/connect_to_mysql.php');


  $err='';

  if($_POST["submit"]){
  
    // Validate form data

    if($_POST["firstname"]=='') $err.='Please enter First Name<br>';
    if($_POST["email"]=='') $err.='Please enter Email<br>';



    if($err==''){ 

      // Check if there are duplicate entries in the 'contacts' table

      $r=mysql_query("SELECT ID FROM Members WHERE firstname='".addslashes($_POST["firstname"])."' and Email='".addslashes($_POST["email"])."'");
      if(mysql_num_rows($r)){
        $err.='Can not add duplicate entry<br>';
      }
      else{

        // adding new record to 'contacts' table

        mysql_query("INSERT INTO Members (firstname,lastname,country,Email) 
                    values ('".addslashes($_POST["firstname"])."','".addslashes($_POST["lastname"])."','".addslashes($_POST["country"])."','".addslashes($_POST["email"])."')");

        // redirecting to success screen

        exit;

      }
    }
  }

I’m not sure if the forum has removed some code (best to use the [ php ] tags around your code), but I don’t see anywhere that would redirect the browser.

You need either a php header() or meta header function.

I agree, from the code pasted above I don’t see what is redirecting anything!
I don’t think you have pasted all the necessary code…
