if (!$LoginODR->EOF) { 

$SecurityLevel = $LoginODR->Fields('Seclevel')->Value; 

$_SESSION['IsValid']="Yes"; 
$_SESSION['security'] = $SecurityLevel; 

}else { 

    $_SESSION['IsValid']="No"; 
    echo "<center>Invalid Username or Password!</center>"; 
    echo "<br><br>"; 
    echo "<form method='post' action='Login.php' name='formcontact' id='formcontact'>"; 
    echo "<center><input type='submit' name='btnback' id='btnback' value='Back' style='width: 150px; height: 50px;'></center>";
