As a routine, I am removing the plugin pages head code from my framework 'parent' page. - which seems to work pretty well for me
Any jscript in the head of the plugin page, I move to the bottom of the page, just before the closing body tag, so it gets included.
However, with the cart checkout page, i noticed there is an includes in the head section...
<?php echo((isset($WA_confirm_cart))?$WA_confirm_cart->Head:""); ?>
can i ask its function and can i safely move it somewhere else ?
