Once again, you should begin at the top of the menu, 'The "cartpage" Template' and work your way down. You will have to skip ahead to add products in order to test your integration if there are no products in the database now. We have an example "cartpage" template named template.cfm in the "store" folder (you may have renamed the store folder). We use this file for testing so you will have some debugging info at the bottom until you remove it. Point your browser to your web site at.
http://www.abc.com/store/template.cfm
You're welcome to work with this template and rename it and change it and use it all you like. We suggest that if you already have a site, a simpler method is to copy a page from that site and then copy the various snippets of code that you need while following the instructions for building your own cartpage.
The custom tags we reference in this documentation are located in the extra_stuff/Custom_Tags_with_Styles folder. Those are the only tags covered in this documentation. Some are also in the "store" folder you uploaded.
As always, if you get a bit overwhelmed or confused about something, email us at buddy@twcreations.com with your questions. We're always glad to help!
