Dear DrAmine,nthank you for your answer. But I don´t understand it exactly.nMy wish for the second UDF is to return the same value like in source1. In the example above, the value 1 and then multiplicate this value.nI don´t know why this values don´t get transferred and also have no idea in which way a second UDMI can solve it...sorry for thatnBest regardsnisaps1860nn
