TOPIC: payment totals

I have a cleint that wishes to take booking for car services, and i was thinking of using this component.

The features i need to make sure are available are as follows.

The user will select car make, then model, and type of service, the system would them show them a price and they can then book the service,

there will be many makes and models and two types of service would dt register be able to give the price of the service by the user selecting the options.
