Thanks again Noppie, I appreciate your help with this!

My config file is softball-baseball-bats.com_config.php (and one for the www.) and looks like:

<?php
define('STORE_NAME','Softball Baseball Bats'); //Store Name
define('STORE_OWNER','Softball Baseball Bats'); //Store Owner
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');
$template_dir = "softballbaseballbats";
define('SITE_NAME','softballbaseballbats');
define('HTTP_SERVER', 'http://softball-baseball-bats.com');
define('HTTPS_SERVER', 'https://softball-baseball-bats.com');
define('CATEGORIES_ROOT','0'); //root categories is 1 for this site
?>

We have some differences but it looks pretty much like the sample that came with the mod.

I suspect it's probably the category_root thing but all the products should show on all the sites so that *shouldn't* be an issue - or - it's in the add-on setup.

The addon points to the root cuz that's where Zen is installed, and all the categories have been assigned to both sites.

Then again I'm the one with problems so what do I know? :)
