You'll need to pick up the /ajax.php and /YOUR_TEMPLATE/jscript/jscript_framework.php at a minimum to make sure that the OPC AJAX calls are properly handled.
Many thanks Cindy - I have installed the plugin and all 'looks' good excepting when clicking the 'confirm the order' button nothing happens, there is no action, so I have done something wrong I guess .... the /ajax.php - pardon my ignorance but where should that file be installed? - I have put it in includes/classes/ajax folder (zcAjaxOnePageCheckout.php is in this folder also)

So close and yet so far

cheers,
