Yeah, I figured as much, but the code is copied right off the referenced page.

From: http://en.wikibooks.org/wiki/Haskell/Applicative_Functors
============================= import Control.Applicative
f :: (a -> b -> c) fmap :: Functor f => (d -> e) -> f d -> f e fmap f :: Functor f => f a -> f (b -> c) -- Identify d with a, and e with (b -> c)
sumsqr :: Int -> Int -> Int -- my f sumsqr i j = i*i+j*j =============================
The line with the error is the one beginning with "fmap f :: ..."; you can't provide a variable/parameter on the left hand side of the :: Also, why are you trying to re-define fmap? -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
