Hello,
In order for the Shipping and Payment details selection to appear on the listing page, you must first select a template that supports this feature. This is either your own custom template which includes the [SHIP_PAY_DETAILS] tag, or one of our standard templates that displays the section 'Your shipping and payment details will be inserted here.' on the template selection screen. If you do not choose a template, or choose a template that does not support the shipping and payment details section, then the section next to the Sellathon counter will be hidden. I hope that helps!
