Calculations can be easily performed on your Input Table. Here’s how it’s done:

  1. In Form Builder, select your Input Table and click on Gear icon.
  2. Then, in the Input Table window that opens on the right, under the Options tab, enter your values in the Calculation Values field. Separate the values with commas for columns and break lines for rows.
