[Haskell-beginners] error: Not in scope: data constructor `BinTree'

[Kak Dod]

Thank you but

if I change the code like this:

data BinTree a = Node BinTree a BinTree a | EmptyBinTree deriving Show

b1 = Node 3 EmptyBinTreeEmptyBinTree 

Then I am get this error:

bintree.hs:1:23:
    `BinTree' is not applied to enough type arguments
    Expected kind `?', but `BinTree' has kind `k0 -> *'
    In the type `BinTree'
    In the definition of data constructor `Node'
    In the data type declaration for `BinTree'
Failed, modules loaded: none.

Your constructor is called Node, not BinTree.
data BinTree a = Node a (BinTree a) (BinTree a) | EmptyNode
b1 = Node 3 EmptyNode EmptyNode
