eCart6 Add to Cart button to replace Add to made by Data Assist: Bindings Panel Not Showing All Fields

I'm following eCommerce Tutorial II ( http://www.webassist.com/tutorials/Add-a-shopping-cart-II-eCommerce-Series ). Found all the code (matched exactly the line numbers shown in the tutorial!) to delete the existing DataBridge-created "Add to Cart" button on the products_detail page. When I get to bindings, there's no pick for either thumbnail or shortdesc.
What am I doing wrong?

I got results.php and details.php to pull the correct info. But maybe I'm set up wrong there, too. I started with the eCommerce starter set of tables, but then found that both DataBridge and eCart expect additional fields —metakeywords, for example, are not found in the model database. I added a column for that.

When running the wizard, you must not have edited the product results page settings to have it include the thumbnail and short description columns.

you can add them easily enough by editing the WADAProducts recordset and selecting any of the missing columns that you would like to have included.

Thanks!

you're welcome.
