A custom age or other answer is rejected for an event

In GiveCampus Events, available controls depend on your permissions and the interface used by your institution.

Use the generated template and exact question label (including the required-field marker where supplied). Dropdown values must match the question's configured choices; multi-select answers are validated against those choices. A number field accepts digits, so a bare 6 passes that particular numeric check. That does not prove it is a valid choice for an Age dropdown or that the whole row is valid. Inspect the actual field type, choices and row error before changing a value; no universal minimum age follows from this importer.
