Hi @Leo.B
We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a real picture as your avatar because it helps build community!
Looping through selected options is not a problem you can find a sample form here Can I select 5 Choices, and then the repeat loop happens only for those 5
but in your case you need the opposite which is not that easy. If that set of options is not big I would rather build your form without using repeats, it would be something like:
not_selected_loop (1).xlsx (7.4 KB)
does that work for you?
