<pre><code>    session_start();

    $plan = @$_GET['plan'];
    $plan = +$plan; 
    include('connect.php');

            If (isset($_POST['submit']))
            {
            $CompanyName = $_POST['CompanyName'];

            $CompanyEmail = $_POST['CompanyEmail'];
            $CompanyContact = $_POST['CompanyContact'];
            $CompanyAddress = $_POST['CompanyAddress']; 

            $RegistrationType = $_POST['RegistrationType'];
            $Plans = $_POST['plan'];
            $Status = "Active";
    $query1 = "select count(CompanyEmail) from ApplicationRegister where CompanyEmail = '$CompanyEmail'" ;
    $result1 = mysql_query($query1) or die ("ERROR: " . mysql_error());
    //$result1 = mysql_result($query1, 0, 0);
    //echo $result1;
     while ($row = mysql_fetch_array($result1))

                {
                    //$companyemail = $row['CompanyEmail'];
                    //if($companyemail != '' || $companyemail!= 'NULL')
                    //{
                        if($row['count(CompanyEmail)'] &gt; 0)
                        {


        echo "This E-mail id is already registered ";
    }
    else
    {

    $sql = "INSERT INTO ApplicationRegister(CompanyName, CompanyEmail, CompanyContact, CompanyAddress, RegistrationType, ApplicationPlan, ApplicationStatus, CreatedDate) VALUES ('$CompanyName', '$CompanyEmail', '$CompanyContact', '$CompanyAddress', '$RegistrationType', '$Plans', '$Status', NOW() )";
$result = mysql_query($sql) or die(mysql_error());

$id = mysql_insert_id(); 

$_SESSION['application_id'] = $id;


//if(isset($plan == "trail"))
if($plan == "trail")
{

header("Location: userRegister.php?id=$id");
exit();
}
else
{
    header("Location : PaymentGateway.php");
    exit();

<p>When the user entered companyemail is already exists it should display the alert message just below the company email field in the form. But now its displaying in the starting of the page. I dont know what to use and how to use. Please suggest</p>
