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
