You just have a spelling/typo error, "parselnt" (with lower-case "L") instead of "parseInt" (with capital "I").

Also, while space is allowed by the language, it is considered a "best practice" when calling a method to follow a method name immediately by the open parenthesis.

Hi Dennis Eitner ! While we all appreciate your help in the Community, leaving explicit answers that can be copy/pasted directly into a challenge to pass it while not including any explanation is frowned upon. Could you please update your answer to include an explanation? Thanks :sparkles:
