PRIOR

Gets the previous repeat/row value(s) of the named field within a Page/Table, starting from the current repeat context.

Syntax

PRIOR('dataname', occurrences)

Example

PRIOR('myfield') List of all prior answers

PRIOR('myfield', 1) last prior value only

Optional second parameter specifies how many prior answers to retrieve.

Notes

Should only be used within a repeatable Page or Table.

Prior repeat values are returned as a List unless the second parameter is 1; if so the value of the last prior answer is returned. Useful for performing aggregate functions on repeat values thus far (e.g. SUM,COUNT) and, if second parameter is 1, for copying forward the previous repeat/row value into the current new instance.
