Well if you follow the link at the end of the error message, it should explain that BOTH the Field Label and the Field Name have to be correct for the grader to see the name properly so you have to fix both. Yours only says "Contact" for the Field Name. Also, it explains that Field Names can NOT have spaces so when you fix it you need to put and underscore for the space so "Contact_Name". Then, Save and then the grader will see it and update your score - but don't forget to run the scoring routine again in the Developer Console and THEN update the page to see the newer scores, ok?
