Template talk:Infobox concentration camp

"Liberation date" error
Greetings and felicitations. The article "Giado concentration camp" uses the field "Liberation date", which is displayed as "Liberation", but gives the error in preview mode "Preview warning: Page using Template:Infobox concentration camp with unknown parameter 'liberation date. This is IMHO a useful field.  Would someone please fix the error?  Also, I would prefer "Liberation date" over "Liberation".  (Anyone else have an opinion?)  —DocWatson42 (talk) 06:57, 15 July 2024 (UTC)
