Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The reference qualifier must be a script that uses the parent field's value
Options B and E are correct. For a reference field to filter its choices based on the value of another field (cascading), the reference qualifier must be a script that uses the parent field's value (B). Additionally, the parent field must be present on the form containing the reference field (E). Option A is incorrect because the parent field does not need to be a reference field; it can be any field type. Option C is incorrect because, although the fields are on the same form, this condition is already covered by E. Option D is incorrect because there is no requirement for matching field names on the reference table.
