When to choose this
Exact behavior
- Choice fields only.
- Non-empty block-list required.
- Requires non-blank source answer — fail-closed like Not equals.
- Single-select: true when the selected value is not in your list.
- Multi-select: true when none of the selected options appear in your list. If they pick any forbidden chip, the clause fails.

Common mistakes
- Expecting blank to route internationally — add Is empty rule.
- Confusing with Not equals single value — Is none of is the multi-value block-list.
- Empty chip list — never matches.
Troubleshooting
Blank should show international block
Blank should show international block
Add parallel Is empty → Show or Require Country first.
Multi-select partial forbidden

Selecting one forbidden option blocks match — intended block-list semantics.

{A,B} is not exactly negation of Is any of {A,B} for blank — blank fails both.Value mismatch

Confirm chip values match option storage, not display labels only.
