You use the Repeat Every Properties Dialog Box to define the duration after which an activity will be repeatedly initiated. It is used for the On Alarm activity of the Event Handler element.
The Repeat Every expiration type can be used either along or in combination with either the For or the Until expressions.
This dialog box opens when you select Repeat Every as the alarm type in the Properties window for the On Alarm element and click the ellipsis button (...) next to the Repeat Every parameter.
In this dialog box, enter the number of years, months, days, hours, minutes, or seconds after which the alarm will be repeatedly fired.
