I have a SharePoint list that has a required multi-select column called AgeGroup. I have a flow where I am updating a different column in the list. When I perform the update item step, I update the column that I recalculated, however I also must include the value for the required multi-select AgeGroup column. I want to RETAIN the SAME value that was already assigned to this column from the Get Items. What dynamic content do I use? AgeGroup, AgeGroup Item, AgeGroup Value?
