I have a checkbox lookup question that I will feed into the loop of a repeat group. In the past, I usually use the product of count-selected() function as the repeat count. However this time, I need the opposite. I need to count those items that were NOT selected in the lookup table to use in the repeat group. Has any of you done something like this?
Haven't tried this, but i imagine that if you feel the "Count()" function the same path to your lookup would work in combination with count-selected. counting a property that exists across the board with the same filter that you have for your lookup should yield the number of items in your checkbox questions.
so it's then just a matter of "Count()" - "Count-selected()"
if you end up trying that, please do let us know if it works
