hiya
 
I was wondering how I would get the second function do recursively do the function for poolNews xs.... tried that and it fails.

--Give wins, draws a rating.
 
poolNews :: Result -> PoolNews -> PoolNews
poolNews (a,b,c,d,e) (home,away,goaless,scoredraw) 
             | c > d = (home+1,away,goaless,scoredraw) 
             | c < d = (home,away+1,goaless,scoredraw)  
             |(c == 0) && (d == 0) = (home+1,away,goaless+1,scoredraw) 
                  | otherwise = (home,away,goaless,scoredraw+1)
 

--Do for all Results
poolNewsB :: Results -> PoolNews
poolNewsB (x:xs) = poolNews x (0,0,0,0)
