Select multiple values from listbox and then use match functions
Can I select multiple values from listbox and then use match function in expression? For example, I select 'Code' from the listbox with multiple values 'A' and 'B', and then in a chart expression, I want to use =if(match(Code, 'A','B', 'C','D'), 1, 0). how to do this with multiple selections? I tried with single selection value, it returns 1, but multiple selections always returns 0.
