How can I achieve the following logic

Hi @lamasewidan -

It appears this is a duplicate of the discussion already going on in your other thread here:

how to use recursive and chunk loop in the same time

Hi @lamasewidan , could you share some data and show what the expected results for the first 3 lines, and of course explain how you got to these values? This will help illustrate what you are trying to do, and there might be a more straight forward way to do this instead of using 2 loops nested in one another.

Please continue the discussion there. I will close this thread to help keep the forum tidy.
