Typo in code block of "Error Checking and Exceptions"

[lawrencetheabhorrence]

In the definition of LispVal, there is an error for the definition of showError for NumArgs:
(NumArgs int args) -> T.concat ["Error Number Arguments, expected ", T.pack $ show int, " recieved args: ", unwordsList args]

Instead of "recieved args", it should probably be "received args".

There is also another typo for Expected List: "function" instead of "funciton"
