What am I doing wrong here? I am trying to get the items at these indices at the corresponding rows, but it isn’t working out. I’ve tried almost every single combination of list levels and I’m still not getting the result I want.
Offhand:
-
You don’t have Indices at level 3, but level at 1. Indices are an integer, and @L3 is a list of lists, not an integer.
-
I see nulls and empty lists in both data sets. Either is a sign that you’ve skipped some filtering along the way, and both will cause warnings (you can’t get anything from an empty list, nor can you get an item at a null index).
Both of these are likely easily fixable, but require the larger context of what you’re doing here, and how the data has been put into this state.
I tried this at level 1 as well but it’s still not working out.’
An example of what I want: in the index list, for the first item of the third list, I want to get the item at index 0 from the third list in the list connected to “list”.
