Total on sidebar doesn't work

Nice Calculator, although the Total on sidebar doesn’t work. No matter what choices are selected, the price total stays at $0.00. This is unfortunate because it makes a nice looking form. Also the styling in the admin area is a complete mess, making it confusing and hard to use. Would consider buying if I knew it would work, but there is no guarantee, especially if the free version is broken. Part of me keeps thinking and wishing, maybe the paid version is styled better…and maybe the paid version works! Too bad for me. So so sad!!!
