Doing Sum while you copy the section during Submission

If you use the option to copy a section while submission and want to get a total of some fields of the copied section, use the SIGMA formula in formula block.
Write SIGMA(unique field name of the field to be summed) in the formula block.
For example, suppose we need to sum the line item totals to get a sub total as shown below. The section with Price Per Unit, No. of Users and Line Item Total will be copied during submission and you will get the sum of ‘Total’ Line items in the ‘Sub Total’ blank.
