Users cannot edit their node during checkout

Once a user clicks on one of the products which is assigned to a content type and they fill out the form and proceed to checkout, they have no option to "edit" the node again if need be. The title of the product still links to the original product page(which the user shouldn't see.). Why isn't the edit link appearing to edit the node the user just added to the cart? I'm using a view to display the products pretty basic. nothing fancy.

I just need users to have ability to edit the node .. everything is checked in node checkout settings so i'm not sure what's going on. they also have permission to create and edit content of those contente types.

this is major as i have to get this site live for a client tomorrow.

This is what is not happening for me although it's checked "Options in the module allow you to turn links in the shopping cart into edit links for the node, display a summary of the node details in the shopping cart and on the order screens,
ideas? thanks,
