Repeats running the scheduled item at the specified time interval.

Schedule Type
Interval is already selected.

Repeat the Action Every
Select this option, then use the Hours, Minutes, and Seconds fields to determine how often the action should be repeated. You can leave any of the fields zeroed, but you must have a practical value in at least one of the time increments.

The action (such as sending a Distribution) is repeated at the interval of time you specify. For example, if you specify 1 hour for the repeat action interval, the Distribution is sent every hour.
