I'm trying to learn Haskell from the wikiBooks pages and there was this example code

pts :: Int -> Int
pts 1 = 10
pts 2 = 6
pts x
    | x <= 6    = 7 - x
    | otherwise = 0

When I put in the first line I get this error: :1:1: error: Variable not in scope: pts :: Int -> Int What am I doing wrong?

In the interactive shell `ghci`? – Willem Van Onsem Apr 10 '18 at 19:53
Yeah in that console screen ghci – RuuddR Apr 10 '18 at 19:55
then it is a duplicate, see the reference. – Willem Van Onsem Apr 10 '18 at 19:55
Okay, I will do that – RuuddR Apr 11 '18 at 04:14
