I'm not really technical so I have no idea what to do. I added the age in years, months and days template from Wikipedia so it could calculate tenures in my singing group's wikia. But where it should say how many months they have been in the group I get this red "Expression error: Unrecognised word "strong". " text instead. How can I fix this?
