When I remove the "scoresPassed <- sqlReaderIO" line, the code run smoothly. Nothing else references "scoresPassed". The ghc, however, gives me this error when the line is included:

I think the problem is including that changes cgiTMain to executing in/under another monad; if you specify your types explicitly, it'll help you avoid the changing types problems.
