Some minor revisions with the website. You can check the website from [login to view URL] REVISON LIST 1- The prices does not display decimals. For example in the admin panel we entered special options to the burgers. Special sauce for 1.5 TL But on the front page it rollsup to 2 TL. We want the site to display the exact values. 2- On mobile iphone5. The qucikview and the added to cart dialog box is out of the box. The site is not adjusted for low resoluitons like 640 px. 3- On the order e-mails If the user took out some items from the standart materials by unchecking the selection box......we want the unselected items to be displayed as strikethrough on the email. 4- There are some scripts on phtmls to disable shopping on Sundays. But to make a change (for ex: on national holidays) we need to edit those phtmls. Make that function controlled from the admin. We want to select the open days and hours from the admin page. The phtml list which enables shopping between 12.00 - 22.00 and disables on Sundays and /app/design/frontend/base/default/template/sales/order/info/[login to view URL] app/design/frontend/mgstheme/burger/template/checkout/onepage/[login to view URL] app/design/frontend/mgstheme/burger/template/sales/order/[login to view URL] app/design/frontend/mgstheme/burger/template/sales/order/[login to view URL] app/design/frontend/mgstheme/burger/template/bhc/[login to view URL] app/design/frontend/mgstheme/burger/template/catalog/product/view/[login to view URL] app/design/frontend/mgstheme/burger/template/checkout/[login to view URL]
