The indentation is not right; all the statements after the 'do' keyword need
to start exactly at the same column. In particular, the 'f' in fileContent
and 's' in set should be one below the other. And the 'return ()' also seems
to be displaced; perhaps you want that also exactly below the last 'set' if
it's the part of the last case.
Hope it helps

hi, im working ona project, and im having problem loading some code in wxhaskell:
onOpen :: Frame a -> TextCtrl b -> MenuItem c -> StatusField -> IO () onOpen f sw mclose status = do mbfname <- fileOpenDialog f False True "Open image" fileTypes "" "" case (mbfname) of (Nothing) -> return () (Just (fname)) -> do fileContent <- readFile fname
set sw [text := fileContent]
set mclose [enabled := True]
set status [text := fname] return ()
i keep getting the error : "the last statement in a 'do' construct must be an expression." ive tried rearranging it many times, but i still get the same error. any help would be greatly appreciated.
