Hi @adext

Did you initialize the list variable as New List(Of String)

Hi @adext

Before looping through the list to add the items did you initialize. If possible share the screenshot of the flow.

You can’t. You’ll have to create a secondary list, add items to it during the loop, then after the loop you can concatenate them so it’s all in one.
