This FamilySearch record provides source #3 in my profile of Agustis Henry Adam (1866-1952). The indispensable WikiTree Sourcer (love it!) consistently creates this source citation from it:
* "Michigan Marriages, 1868-1925", citing Marriage, Flint, Genesee, Michigan, , Citing Secretary of State, Department of Vital Records, Lansing; FHL microfilm 4207808, {{FamilySearch Record|NQ7B-5MY}} (accessed 7 August 2022) {{FamilySearch Image|S3HY-DZHS-F2F}} Image number 361.
Unhappily, this citation generates a DB_ERROR_897:
invalid format: ^[A-Z\d]{4}-[A-Z\d]{4}(-[A-Z\d]{1,4}(-[A-Z\d]{1})?)?$: Numbered parameter: 1 (record)
{{FamilySearch Image|S3H-DZHS-F2F}}
Either the error checking or the WikiTree Sourcer seems to need fixing. I suspect it's the latter because clicking on the image link in the citation results in an error from FamilySearch.
Your help is appreciated!
