<p>Not sure what I need to do in this situation as I have tried a few ways to fix this.</p>

<pre><code>if(!preg_match("/^[a-z0-9]+([_\\.-][a-z0-9]+)^/" ."@"."([a-z0-9]+([\.-][a-z0-9]+)*)+"."\\.[a-z]{2,}"."$",$email ))
{
    $response="You entered an invalid e-mail.";
    $form_success   = FALSE;
}
