The FormConnect Pro app has a feature called “field calculations”. It allows you to calculate the difference between two or more fields. It works similarly to how a spreadsheet calculates two or more fields. Most users incorporate this feature when they sum two or more numbers but it can also be used to calculate the difference between two dates or two times. In the example below, one of our customers has created a time card that totals the number of hours that an employee worked by calculating the difference between the start and end time.
