Hi @an_ju,
Have you considered using a choice filter rather than constraints? Here’s something that might work for your situation:
survey
| type | name | label | calculation | choice_filter |
|---|---|---|---|---|
| calculate | c1 | concat(${visit}) | ||
| begin_repeat | visits | Visits | ||
| calculate | c2 | substr(${c1}, 0, position(…) - 1) | ||
| select_one visits | visit | Visit | not(contains(${c2}, name)) | |
| end_repeat |
choices
| list_name | name | label |
|---|---|---|
| visits | 0 | Visit 3A |
| visits | 1 | Visit 3B |
| visits | 2 | Visit 3C |
