 * Hello, I have WordPress with woocommerce. I would like to have a small calculation
   to be used only in the back end, perhaps using custom fields or using WooCommerce
   custom attributes.
 * I would like to be able to:
    Let shopmanagers/backend users manually enter a 
   total sales figure. a calculator on another custom field to take off a sales 
   commission and display 10% of the total sales figure. Another custom field to
   display the difference. (total sales figure – sales commission.
 * I only want this to be displayed in the backend only.
