Jason,
I found the bindings panel for WA_Store_Cart when I opened the checkout_form.php file in the plugins folder.
I have two more (hopefully last on this issue) questions: Do I replace the item name between the quotes in the js with <?php echo $WA_Store_Cart->DisplayInfo("Name"); ?>?
And if so the js script resides on checkout_success.php, will this work? I could not find the WA_Store_Cart bindings when I opened this page.
Thanks,
Rob
