Returning list of option choices which were not selected in previous multi select question

Support

I'm facing problem in finding a workaround for the following question for quite some time:

I have 2 multi select questions with same set of options. What I want is the 2nd question to show only those options not selected in 1st question.
For example:
1-select_multiple brands
A
B
C
D
E

If respondent selects A & E then q2 should show:

2-select_multiple brands
B
C
D

I have previously tried name != ${var1} but it works only if I select any one option in Q1

Hello
What I think you can do is to explore the choice_filter column. Then on the second question you can type: not(selected{Q2},name)
That's all. please try it.

thank you @bashirmuheeb
It worked, just a slight change in the code:

not(selected(${Q1},name))
