Missing fields in shopping cart - can't update quantities

Hello,

I've just defined and added my first shopping cart to my Dreamweaver website using the Display Manager. This is my first time using eCart, working with PHP and building an ecommerce site.

As we will only have a small amount of products I'm adding them as static items.

It all seems to be working okay, so far. I can 'continue shopping' and go back and add in another of the same product. But although the shopping cart then increases the total cost and shows the unit price, it doesn't show the quantity or let me update the quantity and there is no 'remove' button. So, if the product is £40, if I go back and add another two to my cart, then when I go back to the cart it just shows Price: £40 Total: £120, which is both confusing and non updateable. I've retraced my steps by creating a new eCart Display Manager and the steps before that and I can't see what I've missed.

My other question is, how do I make changes to my defined shopping cart from Dreamweaver? Can you update it similar to how you can with the eCart Object and Add to cart button by clicking on them in the Server Behaviours tab? I can't seem to find anywhere to change my settings...

Thank you!
