haskell - Parse error on a data type I defined -

I am trying to create a card game in Haskell

I defined the following data types P>

  data rank = R2 | R3 | R4 | R5 | R6 | R7 | R8 | R9 | R10 | J. Q | K | A deriving (affair, Enum, Eq, Ord) data suit = S | H | D | Deriving (Eq, ORD) type deck = [card]   
 C deriving (Gola, Enum, Eq, Ord, Show) data card = Cards (rank :: rank, suit :: suit) > Then I am trying to define constants for a complete deck, such as:  
  fullDeck :: deck full deck = [card (R2, S) ..... .....   
 For every card in the deck with a lot of cards behind it - when I try to compile it, I get the "Pars error error on input R2" error I R2 rank As part of the data type, and I do not know why it is not working properly   
 
 
 You are mixing positional and field notation. Either use:  
  card R2 S   
 or  
  card {rank = r2, suit = s }   
 Expression:  
  card {R2, S}   
 is not valid.  
 
 is an extension that will allow you to type something similar to writing. Specifically, it allows things like:  
  acard = card {rank, suit} where instead of rank = r2 suit = s   
 :  
  aCard = Card {rank = rank, suit = suit} where rank = r2 suit = s   
 However, in this case you  Should  use the field name so that the compiler can guess the field you play.  
 The extension also allows to avoid recurrence in the pattern:  
  F (card {rank, suit}) = ...   
 Instead of:  
  f (card {rank = rank, suit = suit}) = ...   
 The syntax enabled the extension Should be used without.
