I keep getting the following error message, even after trying in 3 new playgrounds: 
Challenge Not yet complete... here's what's wrong: 
Some billing state names do not meet data quality standards, or the data import was unsuccessful.

I followed all of the instructions:
1. Installed unmanaged package in the new playground
2. Added Residential picklist type to Accounts
3. Cleaned up Account list:
a. Removed "Household" from Account name (this wasn't specified, but it didn't seem necessary)
b. Removed duplicate records
c. Changed accounts in ALL CAPS to only cap first letter of first and last name
d. Changed state name to 3 letter State code
e. Saved as .CSV file
4. Imported list using Import Wizard

I received an email confirming the import was successful with 11 rows processed and I see the accounts when I search up accounts in the playground. 

Thanks in advance for any help!

I receive this error when I check my challenge.


Challenge not yet complete... here's what's wrong: 
An account with a related opportunity did not calculate the correct potential value.

The task was to Create a rollup summary field that determines the potential value of the opportunities associated with an account.
Add a custom field to the standard account object that provides a rollup summary of the total expected revenue from all related opportunities.The rollup summary field should be labeled 'Potential Value' and have the Field Name of 'Potential_Value'. The resulting API name should be 'Potential_Value__c'.
The rollup summary should calculate the total expected revenue of all the opportunities related to the account.

Here is a snap shot of my work. Any suggestions as to why this is failing?



Thanks,
Darren
