Next in Collection - Returns the value of the next item in the collection.

For information about collections in variables, see Working with Variables.
 Destination Variable
 Select the variable that contains the collection.

At run time, when the application reaches the end of the collection and there are no more items to return, the system would normally throw a run-time exception.

To prevent this, place a Condition item in the node subflow before this item, and:

Set the Operator property to HasNoMore.
For the Left variable, select the variable that contains the collection.
For the Next Form field, select the next node to go to when there are no more items left in the collection.
