I don't know why Haskell won't compile this

[Shmen]

I'm not sure why Haskell doesn't compile this sections of code.

Could some help me make sense of the logic to make this work

the error haskell gives is " parse error on input = " for the code below


engTeenNumbers:: Int -> String
engTeenNumbers number
| (head number) == 1 && (tail number) >= 4 = english number ++ "teen"

You can't generally make new definitions directly in an interactive Haskell environment. Instead, save them in a file and load them in the way specific to the environment you are using.

You also can't take the head or tail of an Int.
