GetRepetition()

Category: Repeating

Syntax: GetRepetition ( repeatingField ; repetitionNumber )

Parameters: repeatingField ”any repeating field, or an expression that returns a reference to a repeating field; repetitionNumber ”a positive integer representing the repetition number to retrieve.

Description: Returns the contents of the specified repetition of a repeating field.

Examples:

 GetRepetition (RepPercentage ; 2)

If you had a repeating text field called QuoteOfTheDay that contained 20 repetitions, you could extract a random quote using the following formula:

 Let (repNumber = Ceiling (Random * 20) ;    GetRepetition (QuoteOfTheDay ; repNumber) ) 

Comments:

A new shorthand notation can be used in place of the GetRepetition() function. The repetition number can be placed in square brackets after the name of the repeating field. For instance, GetRepetition (myField ; 6) is the same as myField[6] .
