variable product price not changing after selecting dates

Hi I am trying to build a site which lists rooms as products and im using this plugin for selecting check in and checkout dates. I am not able to see a change in price shown(in product page)after selecting the dates of a variable product. i.e, price displayed is same for one night, two night and even for a week. however, correct price is shown in cart and checkout page. Please help, Im building this site to meet my study expenses by renting available rooms. As of now I cant afford any paid stuff.
