How do i use choice filter to select what has not been selected in the previous question?

Dear all,

I have exactly the same problem. I have the inverse logic though: the answer options in the second question should be the ones that respondents did not select in the first question. In both cases, i want the ‘none’ answer option to appear. I tried to replicate the logic that Kal_Lam did in his Choices V2 document. However, for me, it is still not showing ‘none’ in the second question. I also tried to add in Khasaab’s solution, but it’s not working neither. Could someone please help me out?
