My company is building our first store using Prestashop 1.6.9 and we're almost finished. There's just a few minor things we need to fix, but because I'm new to Prestashop, I'm hesitant to go poking around the code on my own. Here are the problems we've been having: On the product page: manually entering quantities causes the “add to cart” button to disappear On the product page: using + and – quantity buttons does not update the price On the product page: updated prices do not display using the $xx.xx format When logged into an account, the shipping carrier is listed as “free” even though “free shipping” is turned off within the carrier settings After clicking “add to cart” from the product page, the cart summary lists total shipping as “free shipping!” even though the product is not set to have free shipping If you are able and willing to take this job, let me know and we can discuss timing and pricing.

I am using the default theme in version 1.6.9 Here is a product page from my store --> http://solutionsbysaly.com/shop/home/11-youtensil-w-logo-case.html

On the product page, there should be two options to change the quantity: press the + and - buttons next to the quantity box manually type in the quantity you want The first option works fine. When I try to do the second option, however, it doesn't work. When I type in a number and click elsewhere on the page, it updates the price but the "add to cart" button disappears. There are no combinations or customization options for this product - it only comes as is. What can I do so that when I manually enter the quantity I want, the "add to cart" button doesn't disappear?
