[Haskell-beginners] problem with type

Am a bit stuck here,... please, what is wrong with this? checkNode :: String -> [String] -> Bool checkNode s nodes = [s == node | node <- nodes ] src/me.hs:3:4: Couldn't match expected type `Bool' with actual type `[t0]' [1 of 1] Compiling Main ( src/me.hs, interpreted ) In the expression: [s == node | node <- nodes] Failed, modules loaded: none. In an equation for `checkNode': checkNode s nodes = [s == node | node <- nodes] thanks, Miro
