Thought I had this done, but obviously doing something wrong as although the flow is processing, the fields of the 2nd List are not being updated.
When user selects an option from a 'Choice' column in a Sharepoint List, I want to add that new value to a field in another Sharepoint List. The individual record line in each list has the same Unique ID for matching.


Expression: length(body('Filter_array')) | |
