@Kal_Lam how can I make the choice “None of the above” disappear or restrict its selection when other choices are selected? I have seen other solutions where you can use “not(selected(., ‘none’) and count-selected(.) > 1)”,this doesnt work well for me since “None” is not restricted or de-activated. See the XLS Form the question in the XLS form I am building.
Thanks.

You have already found the available option - if “none” is the name of the choice (not its label!).
- not(selected(., ‘none’) and count-selected(.) > 1).
But your attached file is different.
Another formula would be:
- if( selected(., ‘none’), count-selected(.) = 1, true() ).
You cannot activate a constraint or change the choice_list during editing a field, only when the field loses focus.
