# AgConcatLastPresentValue

Aggregates loop iterations and returns the last present value.

Evaluates each argument in order and returns only the last value that is present and non-blank. If none of the values is present, nothing is returned. If the last present value is a loop, only the value of the element in the last iteration of the loop is returned.

This function requires a loop expression. For more information, see [Loop expressions](https://help.qlik.com/talend/r/en-US/8.0/data-mapper-user-guide/loop-expressions).
