This Example Lab project demonstrates how to use a Data Flow to sum values in a data repeater.

Explanation

This Example Lab project sums the values of items in a data repeater and displays the sum on the Form. This build consists of a Form, a data repeater, a Data Flow, and a main Flow to run the Form. The Form contains the data repeater and allows the user to add/remove books from the list that the repeater shows. The books have a field for price and as books are added/removed, the sum of the price is calculated and displayed. This is accomplished with a Data Flow on the Form that takes the books in the repeater as input, sums the prices, and returns the sum as an output.
