Hi Aleksandar This line looks wrong
return $ Number . read $ x
Try this
return $ Number $ read x
If that doesn't work then I'm not sure. The tutorial was written for Parsec 2 but it looks like you are using Parsec 3. In practice there aren't many differences to users at least once you import the right see of modules (the modules to import are slightly different). Maybe you could post your whole module if there are still problems. Best wishes Stephen
