Form Builder has a powerful new feature that lets you display summary information for Repeating Lists and Grid Views. You can use and display them within formulas. For example, if you have a repeating list with numeric entries, you will see options for calculating a Sum, Minimum, Maximum, Average and Concatenation. This feature is available for textboxes, dropdown menus, date pickers, time pickers, and checkboxes. As you might expect, not all summary operations are available for all field types (e.g., a date field will allow for a Minimum and Maximum, but not a Sum).
