The only software from the checkout_shipping directory above needed to support this plugin is that added to that directory to support this plugin. So namely first the javascript file and then possibly some of the code that is inside the header_php.php file, but not that entire file.

I've been working on a slight rewrite to pull code out of that file and make a few other improvements.
By "all files", I mean I copied from the plug-in to the checkout_one and nopt from the store:

jscript_calendar_head.php
jscript_b-calendar.js
jscript_a-mootools.js

This was suggested here because the calendar was not displaying.


The plug in file I downloaded do not include any header_php.php file. The plug in works great with OPC off. It just won t register the date into the order when OPC is on.
