Simple daily rental?

I’m trying to set up something to simply allow people to rent an item or items for the day. Times are irrelevant – they come in and use something for that day. The hourly thing is not calculating correctly, and the general price is still displaying $0 for a rental that day. How do you configure this to allow something to be rented for that 1 day? (Start date = finish date)

Any chance anyone will answer this..?
