This says getItemFile is an action that returns a string. No arguments.

getItemFile test = ...

And your implementation obviously requires a file path as an argument. You wanted a type signature of: getItemFile :: FilePath -> IO String or perhaps more simply (FilePath is just an alias for String): getItemFile :: String -> IO String Cheers, Thomas
