Hey there - the question you're asking seems to be somewhat broad. Could you provide a link where you are having trouble?

As for Arrays, I do not believe they are enabled on Wikia (assuming you're referring to the Arrays extension, as your attempted syntax matches). The  function is not included in the ParserFunctions extension, which is enabled on Wikia.
