Hi All, 

Im trying to do the second challenge in App Customization  but am getting some Super badge am getting the error "Challenge Not yet complete... here's what's wrong:  Couldn’t find the 'Volunteer Shift' relationship field or it is not configured correctly."
Please, anyone, can anyone tell me which relationships should be created between these objects? I have created a master-detail relationship between them. 


Also, am not clear with this "Shifts with cascading delete and the option of roll-up summary fields." 

Thank you and any help is appreciated.
Thank you in advance. 

Hi! 

I'm going through the Trailhead quizzes, and I've come to the ones that say "Connect to your Developer Edition" in order to complete the quiz.  I have a Developer Edition account set up, but when I try to access it through Trailhead it gives me this message: "Houston, we have a problem... you are attempting to log into Trailhead to complete challenges with an org that isn't supported.  When you are completing Trailhead hands-on challenges, you cannot use a production or sandbox org...." Anways, I'm not sure how to complete the quizzes. (They are under Learn CRM Essentials)  Any insight is greatly appreciated!
