The product price on the checkout page is missing.
VirtueMart 2.0.x includes many various price displaying options that you can selecf from the prices list.
If you do not check the proper price option like product price, discount or tax amount, it will not be visible on VirtueMart checkout page.

Nvaigate Components -> VirtueMart -> Configuration pricing tab and check how price options reflect in the shopping cart.
