Hi,
It perfectly makes sense if the "drop down" box doesn't show anything, you shouldn't have wasted your time to make that video. I would understand the problem if you just said you were using a 3rd party extension in the shopping cart page.
The drop down shopping cart module (that comes with the PureMart) is not a standalone module and requires PureMart stylization on the shopping cart page. Module makes AJAX call to shopping cart page to gather the products that have been added to cart. Since you are using a 3rd party extension on the shopping cart page; this AJAX call doesn't return anything because the HTML schemes are different.
You can't use the drop down shopping cart module that comes with PureMart unless you re-activate the PureMart template stylization on the shopping cart page.
You have only 1 option; use a "standalone" shopping cart module, like this one:
flexiblewebdesign.com/Virtuemart-Modules/Virtuemart-DropDown-Shopping-Cart
(or remove the
mytemplate/html/mod_virtuemart_cart folder and use the Official Virtuemart Dropdown shopping cart module)
"Virtuemart - Flexible Drop Down Shopping Cart" costs $10 and it is a standalone module (doesn't require any specific template and work in all virtuemart systems). But I am seeing, you are one of our regulars, so i am giving this module to you as a gift.
I just added it to your most recent order and sent you the download link.
Download and Use the "Virtuemart - Flexible Drop Down Shopping Cart" module instead, to have the "drop down shopping cart" in your website.
