Currently, we are migrating that site in the wordpress using Kassypea Theme and wp-ecommerce, but we can't copy some of the functionalities.
1. You can choose the product you want here:
http://sheepskinfactory.com/seatcoverselection.cfm?car=7&seattype=22
wordpress equivalent: http://dev.freelanceu.net/ajb/sheepskin/sheepskin-car-seat-covers-2/buick/seat-type-5/
2. after that you'll be redirect here in this page
http://sheepskinfactory.com/superfit.cfm?car=BMW%20&seattype=22&carsid=7
wordpress equivalent: http://dev.freelanceu.net/ajb/sheepskin/home/buick-seat-type-5/custom-fit-seat-cover/
my question is, can we do that functionality in the wp-ecommerce, the same as the original?
