I copied this module to my local wiki (Tamil). When I use this in {{mbox}} as {{#invoke:Message box|mbox}} , I get the following error:

Lua error in Module:Category_handler at line 231: attempt to call field '_main' (a nil value).

Backtrace:
   Module:Category_handler:231: ?
   (tail call): ?
   Module:Message_box:409: in function "setBoxParameters"
   Module:Message_box:539: ?
   (tail call): ?
   mw.lua:553: ?

I can see that the error is in this module at line number 231: Which is:

local data = nsDetect._main(ndargs)

Can someone please help me? --Jayarathina (talk) 15:15, 17 November 2013 (UTC)[reply]
