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.
