I do understand your frustration. However, there is a lot of information for the eCart getting started guide to cover, if you have idea's on how we can make the getting started guide more user friendly, please let us know by submitting your idea here:
Anyway, on to the problem at hand:
Sorry, but these are not the bindings I was referring to. I was referring to the bindings panel in the add to cart server behavior.
Refer back to the section titled "To Insert an Add to Cart button into a catalog page". This section goes from page 28 - 35.
On page 32, step 10 has you bind the Thumbnail cart column to the ItemThumb recordset column:
Bind the remaining shopping cart columns:
Choose Description. Click the lightning bolt and select ItemShortDesc; click OK.
Choose Weight. Click the lightning bolt and select ItemWeight; click OK.
Leave Quantity at the default settings.
Choose Price. Click the lightning bolt and select ItemPrice; click OK.
Choose Thumbnail. Click the lightning bolt and select ItemThumb; click OK.
this is how the thumbnail name is stored in the cart so it can be displayed on cart.php page.
