How to exclude answer options that were chosen in the previous question?

I'm asking 2 questions about the importance of certain attributes of a proposition. First I ask to rank their top 3 most important attributes from a set of 8.
Then I want to ask which one is the least important. I want to exclude the top 3 answers from that list so they're not able to give the same answer to most and least important accidentally.

How do I do this?

Ranking responses are recorded as numbers, so we can use the AIG function to add all items that weren't in the top 3 like this:

AIG(RankingQ, 3)

"RankingQ" being the name of your ranking question, of course.

Hi Zachary, thank you for the answer. I was aware of this function, but I can't figure out how to remove these 3 items from the pre-existing list of 8 items  to create a new list of only 5 items so that they are unique for that respondent.
If you create a constructed list with that line, it should have only five items.
