Ok, everything is working now, minus gridproducts, I made my own table layout for the store page. However I'm testing now, and while shipping is being added properly, taxes are not. I've double-checked that my products do have "taxes" set to "yes". My tax area of settings is fully configured for all of Canada.
When I click on "proceed to checkout". I see my list of items, I see the taxes, but I am not asked anywhere for my billing or shipping address info, although I've specified to ask for shipping address information. I'm assuming that due to lack of address info, tax is not being added to the products although I live in Canada.
I must be missing a checkbox someplace to force Cart66Lite to request billing information before going to Paypal standard. . .
I've followed the checkout procedure all the way to the paypal payment screen, and nowhere along the way am I asked for the shipping address or billing address. So the total amount on the Paypal screen is everything BUT taxes. . .
