php redirect in a contact script

I have a basic contact script (included below). It redirects to a thankyou.html page using the header redirect which is easy, but I want it to also redirect to an error.html if theres an error. Anyone know how I can do this?

Thanks

[CODE]<?php
include(“global.inc.php”);
$errors=0;
$error=”The following errors occured while processing your form input.<ul>”;
pt_register(‘POST’,’Date’);
pt_register(‘POST’,’InquiryType’);
pt_register(‘POST’,’Status’);
pt_register(‘POST’,’HowDidYouHearAboutUs’);
pt_register(‘POST’,’FirstName’);
pt_register(‘POST’,’LastName’);
