I want to add more field in line items box .Now It's working in sum of these three things(unit price*quantity+adjustment) total value display in Total as per calculation. Now i want to use this total value into another calculation for ex:- one drop down will display with these things (+,-,*,%) and one more field i will enter my amount on that text box when i select the drop down into (-) means it will take my new field value to this format (Total amount value- New field value).and then it will reflect in that total amount. Similarly, the total should change based on the arithmetic operators mentioned in the drop down box.
Because your line items functionality is pretty good to use but except this line items only don't have dynamic fields adding method. If suppose this feature will be available on that page means it will be very useful
is there any possibility to perform math operations like add,etc with the calculated field with other field(user typed) ?
