Hi, I'm having some difficulty integrating && within Guards eg:
something :: Char -> Int
something k
| ord k >= 77 && ord k <= 98 = 8
| otherwise = 88
How the heck can i achieve the above without setting off an error?
Cheers.

A:
In Haskell, an identifier starting with an uppercase letter designates a type, whereas a function name has to start with a lowercase letter.

Press the "edit" button and fix the typo then.

Apart from the uppercase `Something`, there's nothing wrong with that snippet. If you haven't already done so, you'll need to import `ord` from the `Char` module.

An identifier starting with an Uppercase letter (`:` too) can also designate a data constructor.
