Hi,
I have list A and List B,
1) List A I filter for Null Values in a column, as if the column is already filled I want to skip over those. (See filter array)
2) Using the filtered values from list A , from A I want to find values from Column "Title" in List B "Control Title". How do I do this?
3) From List B , Return column "Description" to list A. I believe this would be a basic update item from the result of #2?
here is what I have so far -

any help would be appreciated.
