Thread:Extension talk:Scribunto/Scribunto Script Error (2)

I uploaded an infobox template from wikipedia and now I get this error on every infobox on my wiki:

Lua error in Module:Infobox at line 229: attempt to index field 'html' (a nil value).

Backtrace:

(tail call): ? Module:Infobox:229: ? (tail call): ? mw.lua:553: ? (tail call): ? [C]: in function "xpcall" MWServer.lua:73: in function "handleCall" MWServer.lua:266: in function "dispatch" MWServer.lua:33: in function "execute" mw_main.lua:7: in main chunk [C]: ?

I have no idea what this means or how to fix it, can anyone help me out?
