Hi,
In order for this Exercise to work properly you need to first complete the Unit 3 exercise and then complete this one before the sandbox expires. Please jump back to unit 3, Activate a new sandbox, complete the tasks, then jump to this exercise and complete the tasks.
I saw you received an error during the earlier exercise. Try completing it again fresh as sometimes it will give an error whereas most of the time it completes successfully.
Please click Accept Answer if the above was useful. If you have questions or still need assistance please add a comment below.
Thanks.
