Displaying Order ID on checkout success page : <p>I'll like the order id to be echoed on checkout success page of an opencart store. How do I do this? There are similar threads to this but I've tried the suggestions offered, didn't work for me. So I'm including links to the relevant codes here:</p>

<p>My catalog/controller/checkout/success.php is at <a href="http://pastebin.com/wPWau0Kv" rel="nofollow">http://pastebin.com/wPWau0Kv</a></p>

<p>My /template/common/success.tpl is at <a href="http://pastebin.com/5Jfpkur0" rel="nofollow">http://pastebin.com/5Jfpkur0</a></p>

<p>Thanks.</p>
