Cloned Shipping Module not appearing in Admin

Hi all

I HATE posting problems I encounter when I know a thorough search should reveal the answer, but I'm stumped having searched for over an hour.

I am new to Zen Cart but I have a grasp of the basics. New installation, v1.5. I have everything else working, bar this.

I have cloned the Table Rate shipping module to tailor it, but it's just not appearing in my Admin console, leaving me with this:

Note the absence of the right hand panel and the directory text at the bottom.

I have (I believe) correctly cloned the module and language file, but obviously something is amiss.

Here is the module file (zapostoffice.php)

I'm stumped. I've done it about 5 times with the same result.

Are there any admin log files in your /cache folder? A partially-displayed screen in your admin is usually indicative of a PHP parsing error ...

Well, would you look at that..

Here's the error

[25-Jun-2012 14:34:44] PHP Fatal error:  Cannot redeclare class table in /home/pajerxga/public_html/shop/includes/modules/shipping/zapostoffice.php on line 209

Line 209 has a "}" but I know line counts aren't always accurate... Let me hunt for this

Ok found it:

class table extends base {

and

function table() {

also needed to be changed. Seems like a Table Rate clone requires a bit more care...
