Hi, citation/CS1 is getting a familiar error for me: Lua error in Module:Citation/CS1 at line 2525: attempt to call method 'getTitle' (a nil value). Backtrace: Module:Citation/CS1:2525: in function "chunk" mw.lua:425: in function "chunk" I copy-pasted this template and all modules in this namespace (https://en.wikipedia.org/wiki/Special:PrefixIndex/Module:Citation/CS1) to my Wiki (aside from sandbox or doc subpages, ofc), along with Template:Citation and then implemented it on Template:Citation/doc (http://health-and-medicine.wikia.com/wiki/Template:Citation/doc). How do I overcome this error?
