Try **deleting all the rows in the SAARC visit section, then adding your Sri Lanka visit again**. Another applicant with the same “mandatory field” error reported that this fixed it. This is a [reported workaround](https://travel.stackexchange.com/a/104619), so it may depend on the form version.

1. Remove every row, including any empty extra rows.
2. Add Sri Lanka again and enter the year.
3. Enter the number of visits as a digit—for example, `1` if you went once.
4. Try continuing.

If the error persists, save your application details and try reopening it in another browser.
