Thanks, Emmanuel. I had tried :filtered and numerous other paths that seemed close to working but would not take, even when they seemed that they should/would. For example, in this screenshot, I would have expected the “'s” + LinkedIn API fields to appear here as they do most other places I see the LinkedIn variable, but they’re absent from the list (as are all of the other “'s” options):
I do believe I finally figured it out using the “Advanced” filter shown here:
… where I’m assuming “This User” refers to each User row in the repeating group being searched/filtered (as opposed to the “Current User” conducting said search – though I can’t tell for sure because at the moment I’m both that Current User and the only user in the repeating group results!).
