Instead of raising an error, this returns the literal string "RuntimeError: Please enter a number!". [See the updated example solution](https://github.com/ga-wdi-boston/wdi_2_ruby_quiz_string_manipulation_again/pull/16) for how to raise and test for exceptions. Your code would also never reach this line, since if `x` was something non-numeric, Ruby would error out on line 28 saying "can't compare string to number".
