The Exception to the Rule

When I do the write the code of the last example and enter a letter, let say 'a' without the quotes instead of a number I should get "That's not a number!" by I get an error saying that 'a' is not defined.

Any ideas ?

if you enter a without quotes, the interpreter will process that as a variable name, if you have not set a variable a and assigned it something, you will see the error saying a is not defined
