My only workaround is to pass the parameters through the module's args, but it's messy

It should definitely work. Can you give a link to the actual code that doesn't work for you?

By the way, in case the arguments management is beyond trivial, I would recommend using Module:Arguments from Dev

Sure! It's actually not a fandom wiki, but it does use MediaWiki so I figured it was close enough? https://wiki.uooutlands.com/Module:Crafting

We don't have Module:Arguments, though I could probably port it over, that might be the issue acctully

I see. While I personally don't mind, I'm afraid it wouldn't be tolerated to use this forum for something not Fandom-related. I suggest you refer to general MediaWiki help forums, or to StackOverflow.

Yeah that's fair, thanks for your response.
