Website Fix - Flooring Calculator FOR ABHI US

I believe something is not working due to a Javascript error. This was working at one time but I haven’t used it in a while so Im sure a change was made that caused this to stop working. The flooring is priced per square foot and by carton. We show by square foot price because that’s what everyone goes by but you must buy in full cartons so that is why we have the calculator. It is based on the price per square foot and the square feet by cartons. Again everything has already been coded and was working I just need it fixed because the numbers aren’t showing up and when you change anything the totals should automatically be changed. [login to view URL] is the page that the calculator is on and that’s what generates the product info. We import the products via the import in the admin. And the flooring calculator gets activated via products_floor_calc column in database. We use a 1 if it is activated. Also, once I add to cart the proper amounts that were calculated should be added to the cart along with proper pricing but again all the calculations should already be there. I also need the design fixed on the product details page.
